slope = m = %28-8-2%29%2F%28-4--2%29+=+%28-10%29%2F%28-2%29+=+5
==> The equation of the line is y--8 = 5(x--4), or y+8 = 5(x+4).
You can also have y - 2 = 5(x--2), or y-2 = 5(x+2).
Both are correct .

Use the two-point form of an equation of a line:



where and are the coordinates of the given points.

Then do the arithmetic to calculate



which transforms the two point form to the point slope form:
