1.7: Motion in the Coordinate Plane
A triangle ΔABD is reflected across the y-axis to have the image ΔA’B’D’in the standard (x, y) coordinate plane: thus A reflects to A’. The coordinates of point A are (m,n). What are the coordinates of point A’? (-m, n) m, -n) -m, -n) (n, m) Cannot be determined from the given information. 3/25/2017 1.7: Motion in the Coordinate Plane
