The algebraic expression for #1 is

• (x,y) --> (x - 3, y - 2)

• (x,y) --> (x - 2, y - 3)

• (x,y) --> (x + 3, y + 2)

• (x,y) --> (x +2, y + 3)

The algebraic representation for #2 is

• (x,y) --> (x - 3, y - 2)

• (x,y) --> (x + 3, y - 2)

• (x,y) --> (x + 2, y + 3)

• (x,y) --> (x + 3, y + 2)

The answer to #6 is...

• (x,y) --> (-x, y)
