Question

On a coordinate plane, triangle A has points (3, 3), (6, 3), (6, 9). Triangle A prime has points (negative 2, negative 1), (negative 2, negative 2), (negative 3, negative 2).

Answer 1

Answer: Your welcome!

Explanation:

Triangle A prime is a reflection of triangle A across the x-axis. A reflection across the x-axis will switch the sign of the y-coordinates, leaving the x-coordinates unchanged. This means that the x-coordinates of triangle A prime are the same as those of triangle A, but the y-coordinates are opposite in sign. For example, the y-coordinate of the first point of triangle A is 3, so the y-coordinate of the first point of triangle A prime is -1.
