The Solution:
The question requires that we draw a line representing a Rise and another line representing a Run, and thereafter find the slope of the line in its simplest form.
From the given graph in the question, we have the rise and run as below:
To find the slope of the line in its simplest form, we shall use the formula below:

We shall pick the coordinates of two points in the line as below:

In this case,

Substituting these values in the formula above, we get

Therefore, the slope of the line is 1/3
