How do the number line graphs of the solutions sets of and differ?
Answer
A
One graph uses an open circle, but the other graph uses a closed circle. Also, the rays use arrows that point in opposite directions, but they have the same endpoint.
B
They use arrows that point in opposite directions, the rays have different endpoints, and both graphs use open circles.
C

D
