Question

question 11 of 25 if ab is parallel to cd and the slope of ab is - 3, what is the slope of cd? a. 3 b. -1/3 c. -3 d. 1/3

Explanation:

Step1: Recall slope property of parallel lines

Parallel lines have equal slopes.

Step2: Identify given slope

The slope of $\overline{AB}$ is - 3.

Step3: Determine slope of $\overline{CD}$

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

Answer:

C. -3
