Question

ΔABC with vertices A(-3, 0), B(-2, 3), C(-1, 1) is rotated 180° clockwise about the origin. It is then reflected across the line y = -x. What are the coordinates of the vertices of the image?

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

Answer 5

I'd say C.

Answer 6

@golfwaz24: have you tried drawing it? try sketching the coordinates A, B, and C, and then doing the transformations indicated in the problem

Answer 7

... c

Answer 8

Answer 9

These are kinds of reflections:
Reflection across x-axis: (x, y) > (x, -y)
Reflection across y-axis: (x,y) > (-x, y)
Reflection over origin: (x,y) > (-x,-y)
Reflection over line y=x: (x,y) > (y,x)
Reflection over line y=-x: (x,y) > (-y,-x)

I'd strongly suggest that you plot the given poins and then draw the figure based upon those points. Vocaloid has already suggested this.
