Find the slope of JK←→ and LM←→−. Then determine whether the two lines are parallel, perpendicular, or neither. J(1, 9), K(7, 4), L(8, 13), M(-2, 1)

m(JK) =

m(LM) =

Parallel, Perpendicular, or Neither:

perpendicular"

Step-by-step explanation:

We need to find slope (m) of both line JK and LM

Slope has formula:

Lets find slope of JK:

Lets find slope of LM:

we know if we multiply two lines' slope and get -1, they are perpendicular. Let's check:

Hence, they are perpendicular
