Easy way to do it is to look at the constant, the number that does not have a variable, and that will be your y-intercept, so that is your first point. Then, you take your slope and do rise over run. For example, if the slope is 1/4, then you would rise up one, and run right 4. If the slope was -1/2, then you would rise up one, and run left 2, or rise down one and run right 2. This will give you your second and third points and you can easily graph your line from there.
