Answer:
We calculate the slop of a line.
How to find the slope:
Pick any two points on a graph
The formula of slope is [tex]\frac{Y2-Y1}{X2-X1}[/tex]
For example we have two points that contains the coordinates (5,2) (7,4)
Inserting them to the formula would result in:
[tex]\frac{4-2}{7-5}[/tex]
=[tex]\frac{2}{2}[/tex]
Our rate of change is rise 2, run 2.
