Answer:

The answer is B

Step-by-step explanation:

When you reflect it over the x-axis you have to change the coordinates of each number.

Answer:

B. (1, -1), (1, -4), (3, -1)

Step-by-step explanation:

If a triangle is reflected across the x-axis, it's y coordinate values will become negative or positive if it's already negative. It uses the rule (x, -y)

(1, 1) → (1, -1)

(1, 4) → (1, -4)

(3, 1) → (3, -1)

Only B. (1, -1), (1, -4), (3, -1) is correct.
