Question

Select the equations that are parallel and perpendicular to y = -3x - 1 and that pass through the point (3, 1).

A)parallel: y = -3x + 6
perpendicular: y = 1 over3x + 2 2 over 3
B)parallel: y = -3x + 10
perpendicular: y = 1 over 3x
C) parallel: y = -1 over 3x
perpendicular: y = -3x
D) parallel: y =1 over 3x + 1
perpendicular: y = 3x - 1

Answer 1

y = mx + b, m is the slope. The slope is -3. Parallel slopes are the exact same, and perpendicular slopes are negative reciprocals. :]
