(4, -2)

Explanation:

For a reflection across the y-axis, you need to change the sign of the x to the opposite of what it was.

(x, y) to (-x, y)

If C has the coordinates of (-4, -2), to figure out the coordinates of C' after a reflection of the y-axis, we will change the sign of the x.

C' would be located at the coordinates (4, -2).
