Liam must determine the inequality represented by the solution set on the number line.

A number line going from negative 11 to negative 5. An open circle is at negative 7. Everything to the left of the circle is shaded.

Which statement must be true?
The arrow points to the left, so only the Less-than or Less-than-or-equal-to symbol can be used in the inequality.
The solution set includes –7, so only the Less-than or Greater-than symbol can be used in the inequality.
The circle at –7 is open, so only the Less-than or Greater-than symbol can be used in the inequality.
The circle is on a negative number, so only the Less-than or Less-than-or-equal-to symbols can be used in the inequality.
