What is the sequence of transformations that takes you from the pre-image to the image?

• Reflect over the y then reflect over the x

Given: A(-5,-1), L(-3, -2) and T(-3,2). First translate 6 units right and 3 units down. Then reflect the image over the y-axis. What are the coordinates for A''B''C''?

(Hint: Graph it on scrap paper. And do one point at a time.)

• A''(1, -4) L''(-3, -5) T''(-3, -1)

• A''(-1, -4) L''(-3, -5) T''(-3, -1)

• A''(-1, 4) L''(-3, -5) T''(-3, 1)

• A''(1, -4) L''(3, -5) T''(3, -1)
