500

Give the algebraic rule for ALL of the following: Translation, Reflection across the x-axis, Reflection across the y-axis, Rotation 90 degrees, Rotation 180 degrees, Rotation 270 degrees

Translation - (x,y) --> (x±a,y±b)

Reflection(X) - (x,y)--> (x,-y)

Reflection (Y) - (x,y)--> (-x,y)

Rotation (90) - (x,y)--> (y,-x)

Rotation (180) - (x,y)--> (-x,-y)

Rotation (270) - (x,y)--> (-y,x)
