Which choice is the equation of a line that passes through the point (–6, –2) and is perpendicular to the line represented by this equation?
y = −3x + 1
A. 3x + y = 1
B. y = 1/3x
C. y = −3x
D. −3y = −x + 1
isn't the answer to this B, since the negative reciprocal of 3x is 1/3?

Steve,
D also has slope 1/3, but the given point does indeed lie on line B.

Reiny,
I agree,
B is the correct choice.
