Translations and Reflections

The triangles on the grid below represent a translation. To form the image, the pre-image moved

• five units right and three units up.

• two units right and three units up.

• five units left and three units down.

• two units left and three units down.

Which shows this triangle when it is translated two units left?

• 
• 
•

Triangle PQR is reflected across a line, P = (4,-5), and P' = (-4,-5). What is the line of reflection?

• the x-axis
