Find an equation of the line that goes through the points (10,64) and (-7,-55). Write your answer in the form y=mx+b.

Slope, or m = %28-+55+-+64%29%2F%28-+7+-+10%29______%28-+119%29%2F%28-+17%29, or 7
Using the point-slope formula: y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29, the point, (10, 64), and m, or the slope of 7, we get:
y+-+64+=+7%28x+-+10%29
y+-+64+=+7x+-+70
y+=+7x+-+70+%2B+64
