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
