Figure ABCD is reflected about the x-axis to obtain figure A'B'C'D':A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A polygon ABCD has A at ordered pair negative 4, negative 1, B at negative 2, negative 2, C at negative 2 and negative 3, D at negative 3 and negative 4. A polygon A prime B prime C prime D prime has A prime at ordered pair negative 4, 1, B prime at ordered pair negative 2, 2, C prime at ordered pair negative 2, 3 and D prime at ordered pair negative 3, 4. PLEASE HELP WILL MARK BRAINILEST IF CORRECT
