Question

Two lines are perpendicular and slope of the red line is -7, what the slope of the green line?

Answer 1

It would be 1/7. Two lines are perpendicular to each other if their product is -1


-7(1/7) = -1

Hope this helps!

Answer 2

Well the lines are perpendicular so the slope would be the opposite reciprocal. So he other lines slope would be positive 1 over 7
