Question

What is the image of A for a 270° counterclockwise rotation about C?

Answer 1

Answer:

Option A). (7, -1)

Step-by-step explanation:

In the given image if A is rotated 270° counterclockwise about C then we have to tell the new position of A on the graph.

After 270° counterclockwise rotation A will land in quadrant 4 equidistant from point C and parallel to the x - axis.

So new coordinates of point A will be (3+4, -1) = (7, -1).

Therefore Option A). (7, -1) will be the answer.

Answer 2

Answer: Choice A) (7,-1)

The final point will have the same y coordinate as point C, so y = -1. The x coordinate is found by counting 4 spaces to the right of C. So we have x=3+4 = 7. Why 4 spaces? Because this is the distance from C to A.
