Transformation in a Plane

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

• Reflection over the y-axia 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)
