Question

The lines below are parallel. If the slope of the green line is -2, what is the slope of the red line?

Answer 1

Parallel lines have equal slopes, so if green line has slope = -2 then, red line's slope would be equal to -2

In short, Your Answer would be Option A

Hope this helps!

Answer 2

All lines that are parallel to one another share the same slope, meaning that since the slope of the green line is -2 and the red line is parallel, then the red line's slope is A, -2.
