Question

given a line has a slope of $-\frac{4}{9}$, what is the slope of a line parallel to it?
options: $\frac{4}{9}$, $-\frac{4}{9}$, $\frac{9}{4}$

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 $-\frac{4}{9}$, the slope of a line parallel to it will be the same.

Answer:

B. $-\frac{4}{9}$
