Question

Point T(3, −8) is reflected across the x-axis. Which statements about T' are true?

The x-coordinate is −3.

The y-coordinate is −8.

The y-coordinate is 8.

The x-coordinate is 3.

Answer 1

Given that Point T`(3, −8)` is reflected across the `x`-axis.
Point T' is its reflection as shown in the figure.

It is cleat that T' is in the first quadrant. As such both `x and y` coordinates are positive.
Therefore following statements are true

The `y`-coordinate is `8`.

The `x`-coordinate is `3`.
