Question

The slope of a line that is perpendicular to a line whose slope is -2/7 is

Answer 1

the product of slopes that are perpendicular to each other is always -1

\(m_1m_2=-1\)

you are given one of the slope \(m_1 = -\dfrac{2}{7}\), so plug in and solve for other slope.

Answer 2

To find the slope of a line perpendicular to another line, you take the opposite reciprocal.

For example, if the slope is 1. Then the opposite of 1 is -1. The reciprocal of -1, is -1/2

So the slope of -1/2 is a line that is perpendicular to a line with slope 1.
