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)
Line 1: (15, 20), (17, 18)
Line 2: (-22, -18), (-20, -16)
