Question

Look at the graph of a line segment before and after a transformation occurred,

Which statement describes the transformation that could have been made to the line segment?
A. The line segment was dilated by a factor of 1/2
B. The line segment was rotated 180° about the origin
C. The line segment was reflected over the x-axis
D. The line segment was translated 6 units down and 1 unit left

Answer 1

C !

It can't be A because the line does not change length. It's can't be B because if you imagine the movement of the line, when rotated the A and B points would switch side visually. It can't be D because the transformed line segment has not moved 1 unit left.
