Question

Line p passes through (8,-6) and is perpendicular to the line 2x+y=-7.

The slope of line p is?

A- -2
B- -1/2
C- 1/2
D- 2

(How do I solve to find slope)

Answer 1

C) 1/2

Explanation:

The slope of a perpendicular line is the negative inverse.

First, convert the given line to slope-intercept form.

2x + y = -7

y = -2x − 7

The slope of this line is -2. So the slope of the perpendicular line is:

m = -1 / (-2)

m = 1/2
