Question

If a line has a slope of 4/7 a line that is perpendicular has a slope of what?​

Answer 1

-7/4x. This is because to find the line that is perpendicular, you have to find its reciprocal

Answer 2

y = -7/4x

Explanation:

This is correct because to find the perpendicular, you need to find the opposite reciprocal of the slope. In this case, the slope is 4/7, so the opposite reciprocal is -7/4.
