Question

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

Answer 1

Line equation -> \[y = m (x - x_0) + y_0\]
Parallel -> Must have same slope -> -3.
y = -3(x-3)+1

Perpendicular -> Negative reciprocal slope -> 1/3
y = .33333(x-3)+1

Answer 2

PARALLEL



PERPENDICULAR
