SOLUTION: Find the equation of the line that goes through the points (-15, 70) and (5, 10) So far, I have the formula Y2-Y1 / X2-X1 that would be 10 - 70 / 5 - 15 = -60/-10 = -6/-1 = 6

Hi

Using the point-slope formula, m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29

(-15, 70) and 

( 5,  10)   m = 60/-20 = -3

OR

( 5,  10)

(-15, 70)  m = -60/20 = -3      |the results are the same
