How to find slope when there is the y intercept and x-intercept?

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
