Question

question 22 of 25 if $overline{ab}$ is parallel to $overline{cd}$ and the slope of $overline{ab}$ is -3, what is the slope of $overline{cd}$?
a. 3
b. $\frac{1}{3}$
c. $-\frac{1}{3}$
d. -3

Explanation:

Step1: Recall slope property of parallel lines

Parallel lines have equal slopes.

Step2: Identify given slope

The slope of $\overline{AB}$ is - 3. Since $\overline{AB}$ is parallel to $\overline{CD}$, the slope of $\overline{CD}$ is the same as the slope of $\overline{AB}$.

Answer:

D. -3
