The equation of the line is, y = -3x.
What is point slope form of the line?
A line's point slope form equation is y - y1 = m(x – x1). Consequently,
y - 0 = m(x - 0), or y = mx, is the equation of a line passing through the origin with a slope of m.
Let the line passes through the point (1, -3) and having slope of -3.
Consider, the point slope form of the line,
[tex]y-y_1=m(x-x_1)[/tex]
Plug, [tex](x_1, y_1) = (1, -3), m = -3[/tex]
So, the above equation becomes
[tex]y-(-3)=-3(x-1)\\y+3=-3x+3\\y=-3x+3-3\\y=-3x[/tex]
Hence, the equation of line that passes through the point (1, -3) and having slope -3 is y = -3x.

Sarah plays basketball. In her last game, she scored 24 points
from 2-pointers and 3-pointers. She made a total of 10 baskets.
How many 2-pointers and 3-pointers did she make? (Let x
represent the number of 2-pointers she made, and let y represent
the number of 3-pointers she made.)
Taking into account the definition of a system of linear equations, the number of 2-pointers and 3-pointers Sarah made is 2 and 3 respectively.
System of linear equationsA system of linear equations is a set of equations relating two or more unknown values, the goal of which is to determine those values so that the equations are true.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, the values of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.
This caseIn this case, a system of linear equations must be proposed taking into account that:
x represent the number of 2-pointers Sarah made.y representthe number of 3-pointers Sarah made.You know:
In her last game, Sarah scored 24 points from 2-pointers and 3-pointers.She made a total of 10 baskets.The system of equations to be solved is
x + y= 10
2x+3y= 24
It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable "x" from the first equation:
x= 10 - y
Replacing this expression in the second equation:
2×(10-y)+3y= 24
Solving:
2×10 -2y +3y= 24
20 -2y +3y= 24
-2y +3y= 24 - 20
y= 4
Remembering that x= 10 -y, you get:
x= 10 -4
x= 6
Finally, the number of 2-pointers Sarah made is 2 and the number of 3-pointers she made is 3.

please help. what is the equation??
Answer:
y = -x + 4
Step-by-step explanation:
The equation of a line follows the form y=mx+c, where x and y are the coordinates, c is the y-intercept (the value of x where the line crosses the y-axis), and m is the slope.
We are given two points/coordinates - (-3,7) and (1,3) - so we know the following is true for our equation:
7=-3m+c
3=m+c
Rearranging the second equation above, we get c=3-m. Sub this into the first one, and we get
7=-3m+3-m
4=-4m
m=-1
Knowing c=3-m, we can say c=3-(-1)=3+1=4
Having found values for m and c, we can now write our equation:
y = -x + 4

The equivalent monthly rate of the number of security breaches is of 5.31%, using an exponential function.
What is an exponential function?An increasing exponential function is modeled according to the rule presented by the equation as follows:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which the parameters of the exponential function are listed as follows:
A(t) is the amount after t years.A(0) is the initial amount of the function, that is, the amount of A(t) at the reference year of 0.r is the growth rate of the function, given as a decimal.In the context of this problem, considering the increase at an yearly rate of 86%, the parameter rate r is given as follows:
r = 0.86.
Hence the function is defined as follows:
[tex]A(t) = A(0)(1.86)^t[/tex]
One year is composed by 12 months, hence the monthly increase is calculated as follows:
[tex]r_m = (1.86)^{\frac{1}{12}} - 1 = 0.0531[/tex]
The monthly increase rate is of 5.31%.

Answer:
See attached worksheet.
Step-by-step explanation:
The worksheet summarizes the steps for analyzing the data on the graph. Note that a "line of best fit" was drawn to help illustrate the linear behavior of the data, and to better the question concerning hours of sunshine in another British town. There are techniques for ensuring a line such as this fits the actual data as closely as possible. These techniques draw a line that has the least overall deviation from the actual data. For our purposes, a hand-drawn line appears to match the data reasonably well, so we are able to concule that the relationship is liner: There is a proportional change in y for every set change in x. That change is known as the slope. The slope of this liner would represent the direct relationship between hours of sun and maximum temperature.

Function refers the relationship between inputs where each input is related to exactly one output.
Given,
Here we have the function y=3 -1/2x.
Now, we have to plot the graph of the function.
In order to plot the graph of the function, we have to take some sample values for x.
So, we will take the values of the x as -2, -1, 0, 1, 2.
Now, we have to apply the values on the given function then we get,
=> x = -2 => y = 3 - 1/2(-2) => y = 3 + 1 => y = 4
=> x = -1 => y = 3 - 1/2(-1) => y = 3 + 1/2 => y = 7/2 = 3.5
=> x = 0 => y = 3 - 1/2(0) => y = 3 - 0 => y = 3
=> x = 1 => y = 3 - 1/2(1) => y = 3 - 1/2 => y = 5/2 = 2.5
=> x = 2 => y = 3 - 1/2(2) => y = 3 - 1 => y = 2

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 127 millimeters, and a variance of 36. If a random sample of 35 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by greater than 0.5 millimeters? Round your answer to four decimal places.
The probability that the sample mean would differ from the population mean by greater than 0.5 millimeters is 1
How to determine the probability value?From the question, the given parameters about the distribution are
Mean diameter = 127Variance = 36 The actual data value, x = Less than 0.5The standard deviation is the square root of variance
So, we have
Standard deviation = 6
The z-score is calculated using the following formula
z = (x - mean value)/standard deviation
Substitute the given parameters in the above equation
z = (0.5 - 127)/6
Evaluate
z = -21.08
The probability is then calculated as:
P(x > 0.5) = P(z > -21.08)
From the z table of probabilities, we have;
P(x < 0.5) = 1
Hence, the probability is 1.0

The equation of the parabola from the vertex is f(x) = 7(x - 3)² + 5
How to determine the equation of the parabola?The equation of the function is given as
f(x) = 7x²
Also, we have
Vertex = (3, 5)
The form of the equation is given as
f(x) = a(x - h)² + k
Where
Vertex = (h, k)
This means that
Vertex = (h, k) = (3, 5)
Substitute (h, k) = (3, 5) in the equation f(x) = a(x - h)² + k
So, we have
f(x) = a(x - 3)² + 5
This also means that
f(x) = 7(x - 3)² + 5
