Answer:
y + 4 = -3(x + 6)
Step-by-step explanation:
the slope of the given line is 1/3; the slope of any new line perpendicular to the given line is the negative reciprocal of 1/3, which works out to -3.
Using the point-slope formula as a starting point and substituting the coordinates of the point for h and k, we get:
y - k = m(x - h), or
y + 4 = -3(x + 6)
Note: this is equivalent to y = -4 - 3x - 18, or y = -3x - 22
