Which equation describes a line perpendicular to line r that passes through the point (3,-6) x-3y=21, 3x+y=3, 3x-y=15, 3x-y=3

See Explanation

Step-by-step explanation:

Missing in the question is the slope of line r.

We'll assume that the slope (m) of line r is

When two lines are perpendicular, their slope are related in:

The equation of the (3,-6) is:

Where

So:

Make y the subject
