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
 , and  would be -5. The equation is written in slope-intercept form:
 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.
 is the only option with the correct slope, so the answer is D.
