Answer:
There are 2 different ways, depending on the amount of data given;
1st way: When only the line on the graph is given (Without any coordinate points given) then the slope could be found out with the formula of Rise/Run, or Change in y / Change in x
2nd way: When a line and 2 coordinate points are given, the the formula that would be used is: [tex]\frac{Y_2 - Y_1}{X_2 - X_1}[/tex], where X₁ and Y₁ are the coordinate points of the 1st given point, and X₂ and Y₂ are the coordinate points of the 2nd given point.
Hope this helps!
