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 inequality uses a Less-than or Less-than-or-equal-to symbol because the arrow points to the left.
The inequality uses a Less-than or Greater-than symbol because –7 is included in the solution set.
The inequality uses a Less-than or Greater-than symbol because the circle at –7 is open.
The inequality uses a Less-than or Less-than-or-equal-to symbol because the circle is on a negative number.
