Question

The ordered pairs (4,5) and (4,-5) are reflected points. Are the locations of these points reflected on the y or the x axis?

Answer 1

The two coordinates' x variables are the same, while the y variables change. This means that it is reflected over the x axis. Reflecting over the y axis would cause a change in the x variable, as it would have to move sideways, so this can't be the case since the x variable stays as 4 even after the reflection.
