Ms. O'Malley wrote this equation on the board and asked, "Is this a true equation?" x – y = y – x

Lindsey said, "Sometimes it is, and sometimes it isn't."

For each case shown, determine whether this equation is true or false. Check the box if the case is always true.

x ≠ 0, y ≠ 0

x = 0, y ≠ 0

x = 0, y = 0

x ≠ 0, y = 0
