Question

Choose the equation of the line passing through the point (6, -2) and parallel to y = x + 7.

y = x + 8

y = x - 4

y = x + 4

y = x - 8

Answer 1

Why not just go on a online graphing calculator and graph each of the lines to see which one passes through the point and is parallel?

Answer 2

2 parralle equations have the same coefficient. In this case it is 1. ( y= 1*x+7)
So the equation of the line will be y=x+b.
For x=6, y=-2 so b=y-x=-2-6=-8.

Answer: y=x-8.
