The slope is, and the y-intercept is 5.
Answer:
Slope is -2/5 and y-intercept is -1/3
Step-by-step explanation:
To get the slope, we pick any two points and apply the slope formula
The slope formula is;
m = (y2-y1)/(x2-x1)
To get the slope, we select any two points
That will be;
(-3/4, -1/30) and (1/4,-13/30)
Substituting these in the slope formula, we have:
m = (-13/30 + 1/30)/(1/4 + 3/4)
m = 12/30 = -2/5
Generally, the equation of a straight line is;
y = mx + b
m is slope and b is the y-intercept
We already have the slope, to get the y-intercept, we select any of the points
-3/5 = -2/5(2/3) + b
= -3/5 + 4/15 = b
b = (-9 + 4)/15 = -5/15 = -1/3
Slope is -2/5 and y-intercept is -1/3
Answer:
A
Step-by-step explanation:
The slope is -2/5, and the y-intercept is -1/3.
A pizza buffet has prepared 18 pizzas to place on the line at the beginning of lunch at 11:00 a.M. The equation y 14x + 18 can be used to describe the total number of pizzas that have been placed out on the buffet line, where x represents every 9 minutes after 11:00 a.M. Which statement best describes the rate of change in the number of pizzas set out on the buffet?
Answer: b. Every 18 minutes, 28 more pizzas were set out on the buffet.
Step-by-step explanation:
The equation is in the form: y = mx + c
m is the gradient which represents the rate of change per a given value of x.
x here is every 9 minutes after 11:00. Every 18 minutes therefore will give x a value of 2 because 18/9 = 2.
The rate of change every 18 minutes is therefore;
= 14 * 2
= 28 pizzas

Jeremy has heard a lot of people in the club talking about tackling a 950-foot rock formation. Jeremy has set a limit that they won’t climb anything that takes longer than 7 hours, so they have enough time to travel to and from the place. Will it be possible to climb a 950-foot rock formation within Jeremy’s time constraint? Explain why or why not.
Answer:
No
Step-by-step explanation:
The amount of minutes to climb up 1 foot of height would take around 2 to 3 minutes. if you divide 950 with 2, you get 475 which would be the time in minutes it takes to climb, if we convert 475 minutes to hours, it would be an estimate of 7.92 hours. So as we see they would need an extra 92 minutes to climb the full 950 feet. If you were able to climb it at an average rate of 135.7 ft/hr, you could make it.

Triangle ABC has side lengths 8 cm, 17 cm, and x cm. The side length of x is shorter than the longest side. What does the value of x need to be in order for the triangle to be considered a right triangle?
Answer:
8 cm and 15 cm
The measure of the side is 15 cm
The measure of the right angle triangle is 8 cm, 15 cm and 17 cm
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the triangle BC = 8 cm
The height of the triangle be AB = x cm
The hypotenuse of the triangle AC = 17 cm
So , for the triangle to be a right angle triangle ,
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Substituting the values in the equation , we get
AC² = AB² + BC²
So , AB² = AC² - BC²
On simplifying the equation , we get
AB² = 17² - 8²
AB² = 289 - 64
AB² = 225
Taking square roots on both sides of the equation , we get
AB = 15 cm
Therefore , the value of x is 15 cm
Hence , The measure of the side is 15 cm
The measure of the right angle triangle is 8 cm, 15 cm and 17 cm

All tickets to a play have the same cost. A group bought 6 tickets and paid a total of $99. Write a multiplication equation that can be used to determine cost c in dollars for each ticket.
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The multiplication equation to determine the cost C in dollars of each ticket is C = 99 x 1/6.
The cost of each ticket is $16.5.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
Example:
6 miles in 2 hours
0ne hour will be 3 miles.
We have,
6 tickets = $99
Divide both sides by 6.
1 ticket = 99/6
1 ticket = $16.5
The multiplication equation to determine the cost C in dollars of each ticket:
$C = 99 x 1/6
Thus,
The multiplication equation to determine the cost C in dollars of each ticket is C = 99 x 1/6.
The cost of each ticket is $16.5.

Which of the sets of ordered pairs represents a function? (5 points) A = {(1, −5), (8, −5), (8, 7), (2, 9)} B = {(7, −4), (7, −2), (6, −3), (−9, 5)} Only A Only B Both A and B Neither A nor B
Answer:
We conclude that Neither A nor B represents the function.
Hence, the correct option is:
Neither A nor BStep-by-step explanation:
A function relates an input to an output.
For example, a certain animal grows 30 cm each year. Thus, the height of the animal is associated with its age using the function
h (age) = age × 30
Therefore, if the age of the animal is 3 years, the height is:
h(3) = 3 × 10 = 90 cm
Set A
A = {(1, −5), (8, −5), (8, 7), (2, 9)}
Please check that there are duplicated inputs.
i.e. x = 8 is appeared twice.
Thus, set A does not represent the function because the function has repeated inputs or x-values. In other words, each input is not related to exactly one output.
Therefore, the set A of ordered pairs does not represent a function.
Set B
B = {(7, −4), (7, −2), (6, −3), (−9, 5)}
Please check that there are duplicated inputs.
i.e. x = 7 is appeared twice.
Thus, the set B does not represent the function because the function has repeated inputs or x-values. In other words, each input is not related to exactly one output.
Therefore, the set B of ordered pairs also does not represent a function.
Conclusion:
We conclude that Neither A nor B represents the function.
Hence, the correct option is:
Neither A nor B
