Question

On a coordinate plane, a triangle has points A prime (negative 2, 10), B prime (negative 6, 4), and (negative 10, 8). What is the pre-image of vertex A' if the image shown on the graph was created by a reflection across the line y = x? (10, –2) (–10, 2) (–2, –10) (2, 10)

Answer 1

Answer:

  (10, -2)

Step-by-step explanation:

Reflection in the line y=x causes the x- and y-coordinates to be swapped.

For A'(-2, 10), the coordinates of A are (10, -2).
