Identifying Parallel and Perpendicular Lines

Avg difficulty 2.5

Given the functions below, identify the functions whose graphs are a pair of parallel lines and a pair of perpendicular lines.

f(x) = 2x+3 h(x) = −2x+2 g(x) = 1 2 x−4 j(x) = 2x−6 \begin{aligned}f \left(x\right) & = & 2 x + 3 & h \left(x\right) & = & - 2 x + 2 \\ g \left(x\right) & = & \frac{1}{2} x - 4 & j \left(x\right) & = & 2 x - 6\end{aligned}
