I am pretty sure the answer would be (a)
Answer:
2
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(6 + 6) / (2 + 4)
12/6
= 2
So, the rate of change is 2
I believe it would be 1.5 cm squared because 7.5/5 = 5
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept → (0, b)
The formula of a slope:

We have two points (8, -4) and (0, 2) → b = 2.
Calculate the slope:

Therefore the equation of a line t in the slope-intercept form is:
