Question

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

Explanation:

Step1: Identify coordinates of U

From the graph, point \( U \) is at \( (2, 1) \) (x=2, y=1).

Step2: Apply reflection over x - axis

The rule for reflecting a point \( (x, y) \) over the x - axis is \( (x, -y) \). So for \( U(2, 1) \), the reflection \( U' \) will be \( (2, - 1) \).

Step3: Plot the point

On the coordinate grid, find the point with x - coordinate 2 and y - coordinate - 1 and plot it.

Answer:

The point \( U' \) is plotted at \( (2, -1) \) (you can click on the graph at the position where x = 2 and y=-1 to plot it).
