Quadrilateral ABCD has coordinates A(−2, 0), B(0, 4), C(4, 6), and D(2, 2). What are the coordinates of the image Rx-axis(ABCD) = A′B′C′D′

Answer 1

H Belen,

Do you know the image of any point toward x=axis?

(X , Y) ---------> ( X , -Y)

A(−2, 0)----> A' (-2,0)

B(0, 4) -----> B' ( 0,-4)

C(4, 6)------> C'( 4. -6)

and D(2, 2)--------> D' (2, -2)

by doing that, you have A'B'C'D' and you can show on the coordinate plane

I hope it is useful,
