Question

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

-21
-712
07/2

Answer 1

The slope of y = –3x – 4 is –3. The slope of the perpendicular line is the negative reciprocal. This means you change the sign of the slope to its opposite: in this case to 3.

Explanation:

Answer 2

7/2

Explanation:

The slope of perpendicular lines are opposite reciprocals

You have the slope -2/7, so the opposite reciprocal of this would be 7/2

Remember, opposite means you flip the sign, and reciprocal means you flip the fraction.
