50 POINTS ASAP Determine the line of reflection.

Reflection across x = −4
Reflection across y = 1
Reflection across the x-axis
Reflection across the y-axis

Answer 1

The correct line of reflection that maps the polygon ABCDE to its image polygon A' B' C' D' E' is:

C. Reflection across the x-axis

Step-by-step explanation:

The given vertices of the original polygon ABCDE are:

A(-3, 3)

B(-3, 6)

C(1, 6)

D(1, 3)

E(-1, 1)

The given vertices of the image polygon A' B' C' D' E' are:

A'(-5, 3)

B'(-5, 6)

C'(-9, 6)

D'(-9, 3)

E'(-7, 1)

Comparing the coordinates of the original polygon ABCDE and its image polygon A' B' C' D' E', we can see that the y-coordinates are negated, while the x-coordinates remain the same. This indicates that the reflection is happening along the x-axis, as it is the line that reverses the y-coordinates while keeping the x-coordinates unchanged.

Therefore, the correct line of reflection is the x-axis, as shown by option C. Reflection across the x-axis.
