Line 1 ⇒ y = 8

Line 2 contains points (0, -2) and ( 4, 1)

Slope is [ 1 - -2] / [ 4 - 0 ] = 3/4

Using ( 0, -2) the equation of line 2 is

y = (3/4)x - 2

One possible equation of a line parallel to ine 2 is y = (3/4)x + 5 [there are infiniite possibilities]

A perpendicular line will have a negative reciprocal slope = -4/3

And we can let the line pass through (0, -2)

So....a possible equation is

y = (-4/3)x - 2
