Simple, you have 2 points on a graph. This means that there's a x and y coordinate for each point. Simply label them as x1, x2, and y1, y2.
The formula for a slope: y2 - y1/ x2 -x1.
You can even put the other way: y1 - y2/ x1 - x2, doesn't matter.
In other words, you can simplify it even further to Δy/ Δx
Δ is "delta" which means "a change in"
Slope is also written as "m"
So finally: m = Δy/Δx

Take any two points on the line.
The slope is Δy / Δx
