Answer:
D.
Step-by-step explanation:
When a line is perpendicular to another, their slopes will be opposite reciprocal. For example, 1 would be -1, -3 would be
, and
would be -5. The equation is written in slope-intercept form:

m is the slope, so find the equation with the opposite reciprocal of 3,
:
is the only option with the correct slope, so the answer is D.
The equation of a line for the given slope is
.
Solution:
Given data:
Slope (m) = 
Point = (–2, 0)

To find the equation of the given line in the point-slope form:
<u>Point-slope formula:</u>

Substitute the given values in the formula.




The equation of a line for the given slope is
.
