Which graph shows a triangle and its reflection image across the y-axis?

(1 point)

a. Two right triangles are shown on the coordinate plane.

b. Two right triangles are shown on the coordinate plane.The first triangle has vertices at left-parenthesis negative 5 comma 2 right-parenthesis, left-parenthesis negative 1 comma 2 right-parenthesis, and left-parenthesis negative 1 comma 4 right-parenthesis. The second triangle has vertices at left-parenthesis 0 comma 1 right-parenthesis, left-parenthesis 4 comma 3 right-parenthesis, and left-parenthesis 4 comma 1 right-parenthesis.

c. Two right triangles are shown on the coordinate plane.

d. Two right triangles are shown on the coordinate plane.

b. Two right triangles are shown on the coordinate plane. The first triangle has vertices at left-parenthesis negative 5 comma 2 right-parenthesis, left-parenthesis negative 1 comma 2 right-parenthesis, and left-parenthesis negative 1 comma 4 right-parenthesis. The second triangle has vertices at left-parenthesis 0 comma 1 right-parenthesis, left-parenthesis 4 comma 3 right-parenthesis, and left-parenthesis 4 comma 1 right-parenthesis.

The correct answer is:

b. Two right triangles are shown on the coordinate plane. The first triangle has vertices at (-5, 2), (-1, 2), and (-1, 4). The second triangle has vertices at (0, 1), (4, 3), and (4, 1).
