List the operations you would use, in order, to complete the transformation table.

(Read carefully, you have time!)

• Subtract 2 to from x, multiply the y by 5, then add 7 to y.

• multiply the x by 5, add 2 to the x, then add 7 to the y.

• subtract 2 from x and add 7 to y.

• Add 2 to the x , multiply the y by 5, then add 7 to y.
