Question

which of the following statements is true about the values of the coordinate points in a figure when the figure is reflected over the y - axis?
both the x - and y - values remain the same.
only the x - values remain the same.
both the x - and y - values change.
only the y - values remain the same.

Explanation:

When a figure is reflected over the \( y \)-axis, the transformation rule for a point \((x,y)\) is to \((-x,y)\). This means the \( y \)-value of the coordinate remains the same, while the \( x \)-value changes its sign. So among the options, the correct one is the one stating only the \( y \)-values remain the same.

Answer:

D. Only the \( y \)-values remain the same.
