D. b = 3
Step-by-step explanation:
Given the following data;
Points on x-axis (x1, x2) = 10, 12
Points on y-axis (y1, y2) = 23, 27
First of all, we would determine the slope.
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
[tex] Slope, m = \frac {27 - 23}{12 - 10} [/tex]
[tex] Slope, m = \frac {4}{2} [/tex]
Slope, m = 2
The equation of straight line is y = mx + b
Where;
m is the slope.
x and y are the points
b is the intercept.
To find the intercept, we would use the following formula;
y - y1 = m(x - x1)
Substituting into the formula, we have;
y - 23 = 2(x - 10)
y - 23 = 2x - 20
y = 2x - 20 + 23
y = 2x + 3 = mx + b
Therefore, intercept, b = 3

a shipping company sells large boxes and small boxes. The dimensions of the large box are 3 times the dimensions of the small box.
How does the volume of the large box compare to the volume of the small box?
a) the volume of the large box is 3 times the volume of the small box
b) 6 times
c) 9 times
d) 27 times
Answer:
d) 27 times
Step-by-step explanation:
Let l,w, and h represent the length, width and height of the small box.
Therefore, 3l,3w, and 3h are the dimensions of the large box.
The volume of a rectangular prism, such as a box, is the product of its length, width and height
Volume of small box = l*w*h = lwh
Volume of large box = 3l*3w*3h = 27lwh
So we can see that the volume of the large box is 27 times larger.

Sandra would pay in dollars for the dress is 0.76 c
What is discount ?
discount. if telling in the simple sentence discount means something which u get at lower price by its original price
According to the question,
c×(1 - 5%) × (1 - 20%)
=c×(1 - 0.05) × (1 - .20)
=c × 0.95 × 0.8
=0.76 c
Hence, Sandra would pay in dollars for the dress is 0.76 c

Answer: Y=-5x+3
Step-by-step explanation:
first slope= 0 on the x axis so -2-3=-5
to get 3 you can do 4-1=3 or 7-4 or even 1-(-2)!
Correct answer: [tex]y = 3x -5[/tex]
You don't have to use the whole table in order to find equation. You can use just two points on the table to start.
In order to find the slope, the formula for that is: [tex]\frac{y_{2}-y_{1}}{x_{2} - x_{1}}[/tex]. So, we can start with points (1, -2) and (2, 1). Label (1, -2) as [tex]x_{1}[/tex] and [tex]y_{1}[/tex]; label (2, 1) as [tex]x_{2}[/tex] and [tex]y_{2}[/tex]. Now we can plug the numbers into the formula.
[tex]\frac{1-(-2)}{2 - 1}[/tex] → [tex]\frac{3}{1}[/tex] → [tex]3[/tex] is the slope.
To find the y-intercept, substitute (1, -2) into [tex]y = 3x + b[/tex].
[tex](-2) = 3(1) + b[/tex]
[tex]-2 = 3 + b[/tex]
[tex]-3[/tex] [tex]-3[/tex]
________
[tex]b = -5[/tex] is the y-intercept.
Thus, the slope-intercept equation is [tex]y = 3x -5[/tex]. Hope this helps :) Let me know if you have any other questions related to this problem!
