3x – 2y = 8
y = 3/2 x – 4
home
The product of 3 and a number is equal to -12
3x = -12
x = -4
home
Parallel to x = -5 and passes through
the point (-2, 4)
x = -2

m = 2/3
passes through the point (-6, 1)
y = 2/3 x + 5
home
perpendicular to x = -3 and passes
through the point (5, -6)
y = -6
home
passes through the points (-2, 4) (-2, 8)
