Well the first thing to remeber is that the slope is the rise of a line over the run. Basicall if you have a line that passes through the origin (0,0) and also the point (2,2) then it has risen twice and gone over twice so you are left with the problem of 2/2 which equals one. Also if you have an equation in slope intercept form which is mX+B=Y then m= your slope.
