Question

triangle abc is reflected across the x - axis to create triangle abc. what are the coordinates of b? (4, 5) (4, -5) (-4, 5) (5, -4)

Explanation:

Step1: Identify original coordinates of B

The coordinates of point B from the graph are (4, 5).

Step2: Apply reflection rule

The rule for reflecting a point (x, y) across the x - axis is (x, -y). For point B(4, 5), when reflected across the x - axis, x = 4 remains the same and y = 5 becomes - 5. So the coordinates of B' are (4, - 5).

Answer:

(4, -5)
