Question

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

The x-coordinate is −3.

The x-coordinate is 3.

The y-coordinate is −8.

The y-coordinate is 8.

Answer 1

When coordinates of a point are reflected across `x`-axis, sign of `y` coordinate is reversed while that of `x` coordinate remains same. Hence second and fourth statements are true.
