Do you know the point slope formula?
yup
Ok, so do you know the formula for the slope of a line passing through two points?
no
Ok, so if you have two points. The slope of the line passing through them is: \[Slope = {y_2-y_1 \over x_2-x_1}\] Where \((x_1,y_1)\text{ and }(x_2,y_2)\) are your two points.

so i just have to plug in the x and y values. right?
Yes. That will give you the slope. Then just pick one point and use that slope with the point you chose in the point-slope formula.
ok... thanx
