Arionna needed to graph triangle PQR reflected across the y-axis. Her work is shown below.
Arionna’s Work:
Arionna’s Graph
Which statements identify her errors? Check all that apply.
Arionna did not find the correct point for P’. She should have negated the x-value, not the y-value.
Arionna did not find the correct value for Q’. All points in a reflection will move.
Arionna did not find the correct value for R’. She should have negated the y-value, not the x-value.
Arionna’s red triangle should be reflected below the horizontal axis rather than across the vertical axis.
Arionna switched the order of the coordinates of P’ (3, –7) when she graphed them.
