Question

Point C' is the image of C (-4,-2)under a reflection across the y-axis.
What are the coordinates of C'?

Answer 1

Answer:

The coordinates of point C' are (4, -2)

here's why:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y). So if we use this information with the problem, the original coordinates, (-4, -2), the new coordinates will be (4, -2).

Hope this helped.
