Parallel
2x + 3y = 6 y = -2/3x + 7
Perpendicular
4x + 8y = 16 y = 2x + 17
Parallel
x = 0 x = -2
Parallel
y + 2x = 1 y = -2x - 4
Parallel
y - 2 = 3( x - 1) y - 3x = 9
Perpendicular
y - 9 = 3( x - 2) x + 3y = 15
Parallel
y = -2 y = -8
Parallel
y = -3x + 12 -3x = y
Neither
y = -5x + 7 y = -1/5x - 8
Parallel
y = 1/2x + 2 y = 1/2x -1
Perpendicular
y = 1/5x + 2 y = -5x + 6
Parallel
y = 2/3x - 1 y - 2/3x = 2
Perpendicular
y = 2/3x - 3 y = -3/2x + 2
Neither
y = 2/3x - 4 y = 1 - 2/3x
Neither
y = 2/5x - 1 y = 1 + 5/2x
Neither
y = 3x -4 y + 3x = 1
Perpendicular
y = 4 x = 3
Perpendicular
y = 4x + 1 y = 3 - 1/4x
Neither
y = 5x - 3 y = 1/5x + 1
