The equivalent ratios can be used to create ordered pairs of the form (x,y).
Before we begin, let's take a look at the information given in the ratio table.
| Time (minutes) | Number of Words |
|---|---|
| 1 | 50 |
| 2 | 100 |
| 3 | 150 |
The equivalent ratios can be used to create ordered pairs of the form (x,y). The number x corresponds to the horizontal axis and the number y corresponds to the vertical axis. (1,50),(2,100),(3,150) Let's plot these ordered pairs in a coordinate plane.
Finally, we will draw a line through the points starting at (0,0).
