Relationships Between Variables

The points on the following graph shows the relationship between x and y.

Which rule describes the relationship between x and y?

• Multiply x by 3 to get y.

• Multiply x by 4. Then Subtract 1 from the product to get y.

• Multiply x by 2. Then add 3 to the product to get y.

• Multiply x by itself. Then subtract 6 to get y.
