Question

Analyze the pre-image ABCD. What are the vertices of

the final image if T-1,-2 ly=x is applied to figure
ABCD?
A
B"(3, 2)
C"
D"

Answer 1

A''(3, 0)

B''(3, 2);

C''(1, 1);

D''(1, -1)

Hope this helps :)

Answer 2

A''(3, 0)

B''(3, 2);

C''(1, 1);

D''(1, -1)

Explanation:

y=x

1. A(2, 4)→A'(4, 2)
2. B(4, 4)→B'(4, 4)
3. C(3, 2)→C'(2, 3)
4. D(1, 2)→D'(2, 1)

translation

1 left 2 Right,then subtract 1 from x-axis and 2 from the y axis:

1. A'(4, 2)→A''(3, 0)
2. B'(4, 4)→B''(3, 2)
3. C'(2, 3)→C''(1, 1)
4. D'(2, 1)→D''(1, -1)
