The line y=2x+7 has a slope (m=2).

All lines that are parallel to it also have m=2.

All lines perpendicular to it have a value of m=-1/2 (the negative reciprocal)

So, these lines are parallel to y=2x+7

y = 2x + 8

y = 2x + 5

y = 2x - 20

These lines are perpendicular to y=2x+7:

y = (-1/2)x + 6

y = (-1/2)x -14

y = (-1/2)x
