The slope of a line that is perpendicular to 2x+2y=7

A

-2

B

`-(3)/(2)`

C

`2/3`

D

`3/2`

Text Solution

Verified by Experts

The correct Answer is:
C
Transform the given equation into slope-intercept form: `y=-3/2x+7/2` to see that the slope is `-3/2`. The slope of a perpendicular line is the negative reciprocal, or `2/3`.[2]
