Question

ABC is reflected across x = 1 and y = -3. What are the coordinates of the reflection image of A after both reflections?

(-2, -7) (-2, 7) (7, -2) (7, 2)

Answer 1

option C) (7, -2)

Explanation:

By the graph, the initial coordinates of point A are ( -5, -4)

first reflection along the line x=1, only the x coordinate will change.

the new x coordinate is = x = 7

thus the point becomes (7, -4)

similarly, reflection along y= -3, only the y coordinate will change.

the new y coordinate is = y = -2

thus the final coordinates are (7, -2)
