Change in y over change in x
Explanation:
To make this easier to understand lets make a table
x | y
1 | 2
2 | 4
3 | 6
Now we go back and find the slope. This is really simple as the rise and run is displayed.
- Count the change in x
In this case x changes by 1
2. Count the change in y
In this case it changes by 2
Now put it into rise over run
Rise(y)/Run(x)
your m or slope would be 2/1 or 2
and in a y=mx+b would be
y=2x+b
