Question

Which transformation would change the coordinates of vertex C to (2, −3)?

A.
a translation 4 units down and 3 units to the left
B.
a reflection across the x-axis
C.
a 90° counterclockwise rotation about the point (3, 2)
D.
a 90° clockwise rotation about the origin

Answer 1

The correct answer is:

B. a reflection across the x-axis

A reflection across the x-axis will change the y-coordinate of vertex C from positive to negative, which will result in the y-coordinate being -3. The x-coordinate will remain the same.
