Call one point, point 1 and call the other point, point 2. Formula for slope is m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29.

Slope-intercept form takes the arrangement, y=mx%2Bb. From this, a general formula for b is b=y-mx. Pick either point 1 OR point 2 and substitute for x and y and compute b.

Now you will have the value for m and for b to write the equation for your line.
