Answer:

The slope is 10 (y =10x +15)

Explanation:

When using two coordinates to find the slope of a linear function, I choose (-2,-5) and (2,35) *but you can choose any two.

The formula for finding the slope is y-y divided by x-x.

so... (35)-(-5)=40 NOTE: I did 35 minus -5 but you can also do -5 minus 35.

2-(-2)=4 But just remember to do it the same order for

subtracting the x coordinates.

40/4=10
