First graph your x and y intercept then pick any two points on the line.
that's the equation used to find your slope
Example:
(4,2) (8,6) let's say those are the points you pick from the line
so then you subtract 6-2=4 (6 is your y2 and 2 is your y1)
then subtracts 8-4=4 (8is your x2 and 4 is your x1)
then your left with
if you can reduce the reduce in this case you can which leaves you with
and that's how you find the slope
