60. In the standard (x, y) coordinate plane below, the coordinates of D are (d, k), and the coordinates of E are (e, k). When D is rotated 180° about E, the result is F. In terms of d, e, and k, what are the coordinates of F?

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

Because the abscissa of D and E are the same, the ordinate remains unchanged after rotating 180 degrees, and the distance to E is the distance from D to E, namely ed. Then its abscissa is e+ed=2e-d, so choose J
