What Rule is used to Reflect a point over the X axis?

• (x , y) --> (-y, -x)

• (x , y) --> (y , x)

• (x , y) --> (x , -y)

• (x , y) --> (-x, y)

• ( -3 , 4)

• ( 3 , 4 )

• ( - 3 , -4)

What Rule Represents a reflection across the line Y=x?

• ( x, y) --> (-x , y)

• ( x, y) --> (x , -y)

• ( x, y) --> (y , x)

• ( x, y) --> (-y , -x)
