Question

the rectangle abcd is reflected across the x-axis. what are the coordinates of the vertex d? d( , )

Explanation:

Step1: Find coordinates of D

From the graph, vertex D is at (3, 2) (assuming the grid: x=3, y=2 as per the rectangle's position).

Step2: Apply reflection over x - axis

The rule for reflecting a point \((x,y)\) over the x - axis is \((x, -y)\). For point D(3, 2), applying the rule, we get \(D'(3, - 2)\).

Answer:

\(D'(3, -2)\)
