Question
- p(-3,14), q(2,-1), r(4,8), s(-2,-10)
slope of (overline{pq})
slope of (overline{rs})
types of lines
Step1: Calculate slope of $\overline{PQ}$
Use slope formula $m=\frac{y_2-y_1}{x_2-x_1}$ for $P(-3,14), Q(2,-1)$:
$$m_{PQ}=\frac{-1-14}{2-(-3)}=\frac{-15}{5}=-3$$
Step2: Calculate slope of $\overline{RS}$
Use slope formula for $R(4,8), S(-2,-10)$:
$$m_{RS}=\frac{-10-8}{-2-4}=\frac{-18}{-6}=3$$
Step3: Classify line relationship
Compare $m_{PQ}=-3$ and $m_{RS}=3$: they are not equal (not parallel) and their product is $-3\times3=-9
eq-1$ (not perpendicular).
