In this lesson I will teach you the point-slope formula.  This is a great formula to find the equation of a line.  You will need to have the slope and at least one point that is on the line to use the formula.   I think all students should use the point-slope formula as their primary way to find the equation of a line however you still need to master the other methods as well.   As in all formulas be very careful of the values you plug into the formula.  Also try not to memorize the formula when you practice it at first- once your comfortable on how to use the formula correctly then work on memorizing it.
