Step-by-step explanation:
You want to start by looking for two coordinates and decide which ones you'll use.
Then you want to find the difference between the two y coordinates also known as the rise.
Then you'll want to find the difference between the two x coordinates also known as the run.
After that you'll want to divide the difference of the two y coordinates with the difference of the x.
Hopefully this helps, much love.

8 is from the right side which is subtracted by the 4 in the left equation. Then you divide that by 4 with 2 which results in 2. You end up with 4/2 and bingo!
