Question

What is the slope of a line that is perpendicular to the line shown on the graph?

−2


2

Answer 1

I can’t see the graph — could you upload it or give two points on the line?

Rule: if the given line has slope m, any perpendicular line has slope −1/m (the negative reciprocal).

So:
- If the shown line’s slope is 1/2, a perpendicular slope is −2.
- If the shown line’s slope is −1/2, a perpendicular slope is 2.

If you post the graph or two clear points from it, I’ll pick the correct one.
