Select all the tables that show a proportional relationship between x and y in the ratio table. There are TWO ANSWERS!

• 
• 
• 
• 

Answer explanation

Proportional tables show a consistent constant that each x can be multiplied by to get the corresponding y in the ratio table.

Divide each ratio $\frac{y}{x}$ to see if there is an consistent constant that takes each x to each y in the ratio table.
