Write the equation of the line labeled line 1.
Write the equation of the line labeled line 2.
Write the equation of a line that would be parallel to line 2.
Write the equation of a line that would be perpendicular to line 2.
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
