**Marth**, Sunday, December 20, 2009 at 2:46pmFind the slope, m = (y2-y1)/(x2-x1).

Then use the equation y - y1 = m(x - x1) with either point to find the equation of the line.

**Damon**, Sunday, December 20, 2009 at 4:11pmMarth actually told you a way to do it

slope = m = (6-4)/(6-2) = 2/4 = 1/2

so

y - y1 = m(x - x1)

y - 4 = (1/2)(x-2)

2y - 8 = x - 2

2y = x + 6
