In other words, you want to plot some points on a graph.
The rise is the difference in the y's and the run is the difference in the x's
The rise over the run is another way of describing the slope or gradient or slant of the line.
Do you have some points along with the assignment?
Or maybe an equation?

Given two points (0,0) & (4,2) you need to define the slope of the line through these two points or the slope (m).
Slope (m)=(y2-y1)/(x2-x1)=(2-0)/(4-0)=2/4=1/2=.5
Using the line equation Y=mX+b, with the second set of points (2,4) & the slope (m)=.5 we find the y intercept (b).
2=.5*4+b
2=2+b
b=2-2
b=0 the y intercept.
Y=.5X+0
Graphing this line we have the rise (Y=2) & the run (X=4).
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = .5x).
