For this case, we have:

Where,
m: slope of the linear function
(xo, yo): ordered pair that belongs to the linear function.
Since the lines are perpendicular, then the slope is given by:

Rewriting we have:

The line passes through the point (-2, -6), therefore we have:

Substituting values we have:

Rewriting we have:
Answer:
An equation of the line that passes through the point (-2, -6) with slope -4 is:
option B
