First find the slope of the line through the two given points using: m+=+%28y2-y1%29%2F%28x2-x1%29 where: (x1, y1) = (0, 5) and (x2, y2) = (-3, -4)
m+=+%28-4+-+5%29%2F%28-3+-+0%29
m+=+%28-9%29%2F%28-3%29
m+=+3
The slopes of lines perpendicular to the given line are the negative reciprocals of slope of the given line.
M+=+%28-1%2F3%29
