Question

Determine the slope of a line that is perpendicular to a line with the slope 2/7

Answer 1

-7/2

Explanation:

The slopes of perpendicular lines are negative reciprocals of each other.

To find the reciprocal of a fraction, flip the fraction.

For the negative part, change the sign.

Slope of line: 2/7

Slope of perpendicular line: -7/2
