HELP FASTTTTTTTTTTTT

Marvin reflected this trapezoid over a line, but only 2 of the vertices changed position. Which line could Marvin have used for the reflection?
Question 1 options:


x = 1 (blue line)


y = 1 (red line)


x-axis


y-axis

Answer 1

Blue line.

Explanation:

Two of the points are on the blue line, so only the other two would be reflected over it.

Answer 2

x = 1 (blue line)

Explanation:

The points that dont move are the ones on the line of reflection, here (1, 1) and (1, 4) are on the line and stay the same.

If you had reflected it using the red line, only (1, 1) would have stayed the same
