Figure MNOP is reflected about the x-axis to obtain figure M′N′O′P′: A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A polygon MNOP has M at ordered pair 1, 3, N at ordered pair 2, 1, O at ordered pair 3, 1 P at ordered pair 4 and 2. A polygon M prime N prime O prime P prime has M prime at 1, negative 3, N prime at ordered pair 2, negative 1, O prime at ordered pair 3, negative 1, and P prime at ordered pair 4, negative 2.
