Triangle ABC was created by joining points A(6, -2), B(4, -6), and C(2, -4) with line segments.

Triangle ABC is reflected over the x-axis and then reflected over the y-axis to form the triangle with side lengths x, y, and z.

Which side length is equal to AC?

• x

• y

• z

• Rotation

• Reflection

• Translation

• Dilation
