Describe how it looks when you plot equivalent ratios on a coordinate plane. 

A straight diagonal line would pass through all the points on the coordinate plane. 

500

When plotting ratios on a coordinate plane, which part of the ratio will be the x-coordinate and which part will be the y-coordinate? 

Example: The first part of the ratio is the x-coordinate and second part of the ratio is the y-coordinate. If you have 2:3, 2 is the x-coordinate and 3 is the y-coordinate.
