As we can see, the reflection of the point is at (2.5,- 4.5). Let’s plot our point and its reflection on the coordinate plane.
We can see that the point is located at (2.5,-4.5) after the reflection in the x- axis of a coordinate plane.

More About Coordinate Planes
A coordinate plane is formed by the intersection of a horizontal number line and a vertical number line. The number lines intersect at the origin and separate the coordinate plane into four regions called quadrants. An ordered pair is used to locate a point in a coordinate plane. The first coordinate represents the x-axis and the second coordinate the y-axis.
We want to reflect a point in the y-axis of a coordinate plane. To do this, we keep the same y-coordinate and take the opposite of the x-coordinate.

As we can see, the reflection of the point is at (- 2.5,4.5). Let’s plot our point and its reflection on the coordinate plane.
We can see that the point is located at (-2.5,4.5) after the reflection in the y- axis of a coordinate plane.
