Question

the point v is plotted on the coordinate grid below. plot the point v, the reflection of v over the x - axis. click on the graph to plot a point. click a point to delete it.

Explanation:

Step1: Recall reflection rule

When a point $(x,y)$ is reflected over the $x -$axis, the rule is $(x,y)\to(x, - y)$. That is, the $x -$coordinate remains the same and the $y -$coordinate changes its sign.

Step2: Assume point V coordinates

Let the coordinates of point $V$ be $(a,b)$. Then the coordinates of its reflection $V'$ over the $x -$axis will be $(a,-b)$.

Answer:

To plot the point $V'$, find the $x -$coordinate of point $V$ and keep it the same. Change the sign of the $y -$coordinate of point $V$ and then mark the new point on the coordinate - grid. (Since the actual coordinates of $V$ are not given in the text, the general method of plotting the reflection over the $x -$axis is provided).
