Algebraic Representation of Rotation

Which is the algebraic rule for a 180 degree rotation?

• (-x, -y)

• (-y, x)

• (x -2, y-4)

• (5x, 5y)

Which is the algebraic rule for a 90 degree clockwise rotation?

• (x, -y)

• (y, -x)

• (-y, x)

• (4x, 7y)

What is the algebraic representation that describes this rotations?

• ( x , y )-->( x , -y )

• ( x , y )-->( -x , -y )

• ( x , y )-->( y , x )

• ( x , y )-->( y , -x )
