Question

the point r is plotted on the coordinate grid below. plot the point r, the reflection of r over the x - axis. click on the graph to plot a point. click a point to delete it. answer attempt 5 out of 10 coordinates of r: ( , ) coordinates of r: ( , ) when a point is reflected over the x - axis, the changes sign.

Explanation:

Step1: Identify point $R$

The point $R$ is at $x = - 4$ and $y=-2$.

Step2: Apply reflection rule

For reflection over $x$-axis, keep $x$ - coordinate same and change sign of $y$. So for $R(-4,-2)$, $R'$ has coordinates $(-4,2)$.

Answer:

Coordinates of $R$: $(-4,-2)$
Coordinates of $R'$: $(-4,2)$
When a point is reflected over the $x$-axis, the $y$-coordinate changes sign.
