5. The Coordinate Plane
Sign In
| Point | Reflection in the x-axis |
|---|---|
| (x, y) | (x, - y) |
| (0, -1) | (0, 1) |
As we can see, the reflection of the point is at (0,1). Let’s plot our point and its reflection on the coordinate plane.
We can see that the point is located at (0,1) after the reflection in the x- axis of a coordinate plane.
| Point | Reflection in the y-axis |
|---|---|
| ( x,y) | ( - x,y) |
| ( 0,-1) | ( 0,-1) |
As we can see, the reflection of the point is at (0,-1). Note that the reflection in the y-axis does not change the coordinates of the point. This is supported by the fact that its x-coordinate is 0, and the opposite number to 0 is 0. Let’s plot our point and its reflection on the coordinate plane.
We can see that the point is located at (0,-1) after the reflection in the y- axis of a coordinate plane.
