Before we begin, let's take a look at the information given in the table of values.
Red Blood Cells
600
1200
1800
White Blood Cells

The table of values represents ordered pairs (Red Blood Cells, White Blood Cells). Let's plot them in the coordinate plane!
We plotted these ordered pairs in the coordinate plane. Now let's draw a line starting at (0,0) through the points to show the relationship. Note that the points we drew in the coordinate plane represent the quantity of something. Let's start our graph with an open circle at (0,0) to show this relationship. This is also why we limit our graph to the first quadrant and ignore any negative values.
