Parallel Lines and Perpendicular Lines

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 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)

write the equation of a line that is parallel to y = -7x + 5 and passes through the point (0, 6)

• y = -7x + 6

• y + 0 = -7(x - 6)

• y = 6

• y + 6 = -7(x - 0)

y = 5/7x +2
y = 5/7x - 30
