Choose ALL the lines PARALLEL to the following line: y = 2/9x - 7
y = 2/9x + 8
y = 9/2x -12
-2y = 9x + 8
9y = 2x -18
Write the equation of a line PERPENDICULAR to the line y = 3x + 2 that passes through the point (9, -2)
y = -1/3x - 5
y = 3x-29
y = 1/3x -5
y = -1/3x +1
Write the equation of the line PARALLEL to the line y = 4x - 9 that passes through the point (-2, 4)
y = 4x + 12
y = -4x -4
y = -1/4x + 5/2
Select ALL of the lines that are PERPENDICULAR to y = 3/4x + 9
y = 3/4x - 3
y = -3/4x + 9
y = -4/3x + 8
3y = -4x + 5
4y = -3x + 7
