Question

The figure below is rotated 180° clockwise and then translated right 4 units. What are the coordinates of the image of point P after these transformations?

Answer 1

(2, 5)

Explanation:

P = (2, -5)

Rotating the figure 180° clockwise about the origin means the x-coordinate of P will be negative and the y-coordinate of P will become positive as the figure is rotated from quadrant IV to quadrant II.

Therefore P' = (-2, 5)

Then if it is translated right 4 units, the x-coordinate of P' will be -2 + 4 = 2

So P'' = (2, 5)
