To complete a table of equivalent ratios, you first have to find the ratio of a pair of data and then use this ratio to fill in the missing spots
Once you have the table, each row represents a point
The first pair of data is 4 gallons of red paint and 6 gallons of blue paint, the ratio is 4 to 6, 6/4 = 1.5, that means that you have to multiply the number on the first row by 1.5 to find the number on the second row:
In this case 8 times 1.5 = 12; 12 times 1.5 = 18; and 16 times 1.5 = 24
Now you have the ordered pairs (4,6), (8,12), (12,18) and (16,24)
These are the ones we are going to graph:
