Answer questions 1-5 based on the graph on the right.
1. Reflect the triangle ABC on the line xa-1 and then translate
<2,-5>. Determine the coordinates of B".
2. What are the coordinates of C' when C is reflected on the
y-axis?

4.
Determine the coordinates of B' after a reflection on the line yex. Determine the coordinates of A' after a
reflection on the line y=-x.
Y=x (x,y) → (y,x) B (-5,5)
(5,-2)
V=-x (x,y) → (-Y,-x) A(-3,3)→ A (-3,-)

Answer questions 6-7 based on the graph on the right.
6. Reflect the triangle on the line y=-x. Next, reflect the
triangle ABC on the y- axis. Then rotate the shape 270°
clockwise around the origin. Draw the triangle A'B'C' in the
coordinate plane.
7.Turn the triangle ABC 90° clockwise, then translate it <-8,4>.
Draw the triangle A'B'C' in the coordinate plane.

8. Consider points J (7, -3) and B (4, -9). JB goes under a translation such that J' (2, 8) and B' (-1, 2). Write
the algebraic description that describes the translation.
