Which correctly describes the two transformations that were used to create the image on the graph?

• Reflection over the y-axis and a rotation 90^o counter clockwise

• (x+10, y) and reflection over x-axis

• Rotation 90^o clockwise and a reflection over the x-axis

• Reflection over the x-axis ad a translation (x+6,y)

Answer explanation

A reflection over the y-axis would flip the order of the labels. Then, a 90 degree counterclockwise rotation would turn the figure on it's side.
