1. Find the horizontal change and the vertical change for the translation
P(4,-4) (-4,7)
A. Right 8; up 11
B. Left 8; down 11
C. Right 8; down 11••
D. Left 8; up 11
2. The point c(x,y) is reflected over the x-axis. Use arrow notations to describe the original point and its reflection.
a. (x,y) --> (x,2y)
b. (x,y) --> (-x,y)
c. (x,y) --> (-x,-y)
d. (x,y) --> (x,-y) ••
3. The vertices of ΔABC are A(2, –5), B(–3, 5), and C(3, –3). The triangle is reflected over the x-axis. Use arrow notation to describe the original triangle and its reflection.
a. A(2, –5), B(–3, 5), C(3, –3) --> (2, –5), (–3, 5), (3, –3)
b. A(2, –5), B(–3, 5), C(3, –3) --> (–2, 5), (3, –5), (–3, 3)
c. A(2, –5), B(–3, 5), C(3, –3) --> (–2, –5), (3, 5), (–3, –3) ••
d. A(2, –5), B(–3, 5), C(3, –3) --> (2, 5), (–3, –5), (3, 3

assuming the translation moves the 1st point to the 2nd.
#2 ok
#3 Having gotten #2 right, how can you choose what you did here?
