Liam must determine the inequality represented by the solution set on the number line.Which statement must be true?
A
The arrow points to the left, so only the or symbol can be used in the inequality.
B
The solution set includes –7, so only the or symbol can be used in the inequality.
C
The circle at –7 is open, so only the or symbol can be used in the inequality.
D
The circle is on a negative number, so only the or symbols can be used in the inequality.
