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

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

Write the equation of a line parallel to y = -1/2x + 3 and that goes through the point (4, -1)

• y + 1 = -1/2(x - 4)

• y - 1 = -1/2(x + 4)

• y + 1 = 2(x - 4)

• y - 1 = 2(x + 4)

Write the equation of a line perpendicular to y = 3x - 8 and that passes through the point (-3, -9)

• y + 9 = -1/3(x + 3)

• y - 9 = -1/3(x - 3)

• y + 9 = -3(x + 3)

• y - 9 = 3(x - 3)
