Question

Find the coordinates of the image of each of the following points under the reflection in$X-axis$.

$(7,0)$

Answer 1

Finding the image of a given point reflected in the $\mathit{X}\mathbf{-}\mathit{a}\mathit{x}\mathit{i}\mathit{s}$:

We know that the image of a point $P(x,y)$ under the reflection in the $X-axis$ is given by $P\text{'}(x,-y)$,

where only the sign of ordinate$\left(y\right)$ changes and the sign of abscissa $\left(x\right)$remains the same.

Therefore, the reflection of the point $(7,0)$ in the $X-axis$ is $(7,-0)=(7,0)$
