A triangle with vertices (−3, 1), (1, 5), and (4, 1) is reflected across the 𝑥-axis. What are the vertices of the image? Select all three points

Question

(-3,-1)

(3,1)

(-1,5)

(1,-5)

(4,-1)

(-4,1)

Answer 1

 (−3, 1), (1, 5), and (4, 1)

If you reflect across the x-axis, you negate the y-coordinate, so you get

(-3,-1),(1,-5) and (4,-1)

Answer 2

(4, 1) is the center.

(7, 5)

(11, 1)
