Slope is [tex]\frac{rise}{run}[/tex], where rise is the change in y and run is the change in x.
So to find the slope, count the change in y and change in x, put it into [tex]\frac{rise}{run}[/tex], and simplify the fraction as much as possible.
In this case, in the interval (0, 2), the y changes by 5, and the x changes by 2, meaning the slope is [tex]\frac{5}{2}[/tex], which does not simplify any further.
Hope this helps! :)
