Graphing Points from a Ratio Table Plot the pairs of values on the coordinate plane. A ratio table is just a group of equivalent ratios. The pairs of numbers in the table can be graphed onto a coordinate plane. Step 1: Write the pairs of values in the table as coordinates.
Example
Step 2: Plot the points. The x value tells you to go right and the y value tells you to go up. Step 3: Connect the dots and add arrows to show that you can continue to scale the ratio up or down. The values from a ratio table should create a straight line.
1. Create a ratio table for the ratio 5:1 and plot the pairs of values.

2. There is 1 cup of sugar for every 3 cups of flour in a oatmeal raisin cookie recipe. Create a ratio table that shows how much of each item would be needed when wanting to make more than one batch of cookies. Then plot the points on the coordinate plane.
