Question

Determine if JK and LM parallel, perpendicular, or neither .

Answer 1

Answer:

3 - Perpendicular.

4 - Parallel.

Step-by-step explanation:

$\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$JK = \frac{1-(-7)}{-4-(-10)} = \frac{8}{6} = \frac{4}{3}$

$LM = \frac{-2-2}{-6-(-3)} = \frac{-4}{3}$

Perpendicular, because two lines are considered perpendicular if their slopes are opposite reciprocals.

$JK = \frac{-2-(-2)}{3-11} = \frac{0}{-8} = 0$

$LM = \frac{-2-(-7)}{1-1} = \frac{5}{0} = 0$
