Suppose there are 2 parallel lines on a coordinate plane.

After which of these transformations will the 2 lines remain parallel in the coordinate plane? Select all that apply.

A.) A translation 12 units to the left.
B.) A rotation 270° counterclockwise about the origin.
C.) A reflection across the x-axis.

The answer is A and C

Step-by-step explanation:

A - If you take 2 sticks and move one of them 12 cm/in to the left, they will still be parallel

C - A reflection of the 2 lines across the x-axis is the same as adding 2 more parallel lines to the plane

B - If one line is rotated 270 degrees it will not be parallel to the other line
