Question

Which equation describes the line parallel to y = –7x + 15 that contains P(9, –6)?

Answer 1

Parallel means same slope. So you have to use point slope form. (x1,y1) is (9,-6) and the slope is -7

So it would be

y-(-6)=-7(x-9)

y+6=-7x+63

Solving for y gives you

y=-7x+57

Hope this helps!!!
