First find the slope of the two given points.

X1 = 1x2 = 3

y1= 2y2 = 3

Slope formula = y2 - y1 / x2 - x1

so,

3 - 2 / 3 - 1

M = 1/ 2 (M is the slope)

Now fill in to the equation of a line formula.Equation of a line formula = y - y1= M(x - x1)

Pick one of the previous points. I'm going to pick (1,2)

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

then figure that out :) et voila.
