Question

Point D is located at (3, -4) on the

coordinate plane. Point D is reflected over
the y-axis to create point D'. What ordered
pair describes the location of D'?

Answer 1

When a point is reflected over the y-axis, the x-coordinate changes its sign, while the y-coordinate remains the same. Therefore, if point D is located at (3, -4), its reflection over the y-axis, D', would have the coordinates (-3, -4).
