Question

given a line has a slope of $-\frac{3}{7}$, what is the slope of a line parallel to it?
options: $-\frac{3}{7}$, $\frac{7}{3}$, $\frac{3}{7}$

Explanation:

Step1: Recall the property of parallel lines' slopes

Parallel lines have equal slopes.

Step2: Determine the slope of the parallel line

Given the slope of a line is $-\frac{3}{7}$, the slope of a line parallel to it will be the same, so it is $-\frac{3}{7}$.

Answer:

A. $-\frac{3}{7}$
