Answer:
y = 0.5x-7
Step-by-step explanation:
First we need to find the slope so we use the formula y2 - y1 / x2 - x1 = m
The variable m will represent the slope or rate of change
-2 - (-11) / 10 - (-8) = m
Or
-2 + 11 / 10+8 = m
9/18 = m
0.5 = m
y = 0.5x+b
To find b replace the y and x variables
I will use 10 and -2
-2 = 0.5(10)+b
You should come out with -7 = b
