Answer 1

• x = 1

Explanation:

As we see this is a horizontal reflection.

The reflection line is equidistant from the corresponding vertexes and is the vertical line.

We can find the line by finding the midpoints of AA', BB' or CC'

• 0 + 1/2(2 - 0) = 0 + 1 = 1
• -1 + 1/2(3 - (-1)) = -1 + 2 = 1
• -4 + 1/2(6 - (-4)) = -4 + 5 = 1

The line of reflection is x = 1
