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

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
