Write the equation of a line that is perpendicular to the given line and that passes through the given point.

Write the equation of a line that is perpendicular to the given line and that passes through the given point.

y + 2 =1/3 (x – 5); (–4, 3)

given line is in point-slope form, with slope = m = 1/3; line perpendicular to given line would have slope = -3/1 = -3, so that second line, in point-slope form, would be:  y - 3 = -3(x - (-4)); or y - 3 = -3(x + 4)
