Identifying Transformations from Rule

What is the algebraic rule for the transformation?

Answer explanation

The preimage is located in quadrant I. The orientation's figure changed, but the vertices stayed the same. The figure rotated 90 degrees clockwise.

Describe the transformation.

• Translated 3 units up

• Rotated 90 degrees clockwise

• Reflected over the y-axis

• Reflected over the x-axis

Answer explanation

Analyze the coordinates, notice that the x-values stayed the same, and the y-values are now opposite. Based on this observation, the figure was reflected over the x axis.

What is the algebraic rule of the transformation.

Answer explanation

Analyze the coordinates, notice that the x-values stayed the same, and the y-values are now opposite. Based on this observation, the figure was reflected over the x axis.
