Figure QRTS is reflected about the y-axis to obtain figure Q′R′T′S′: A coordinate plane with two quadrilaterals is shown. Figure QRTS has vertices Q at negative 5 comma 3, R at negative 5 comma 1, S at negative 2 comma 2 and T at negative 2 comma 0. Figure Q prime R prime T prime S prime has vertices Q prime at 5 comma 3, R prime at 5 comma 1, S prime at 2 comma 2 and T prime at 2 comma 0.
