Answer: Choice b) [tex]x \ge 120[/tex]

The graph will involve a closed filled in circle at 120, with shading to the right.

See the diagram below.

============================================

Explanation:

The phrasing "at least" means "that amount or more".

Saying "at least 120" is the same as "120 or more".

Therefore, x = 120 is the smallest x can be. That's why we go for [tex]x \ge 120[/tex] which says that either x = 120 or x > 120.

Visually, we'll plot a closed filled in circle at 120 on the number line. The shading will aim to the right to indicate all values larger than 120. The closed/filled in circle is to represent we include 120 (as opposed to an open circle where we exclude it).

Due to the fact that your teacher gave you a blank number line, the placement of 120 doesn't really matter.

Number the lines by 60’s. The numbers on the left are negative and the numbers in the right are positive. Also, put a middle dot i t eh middle. Now, go two lines down (60, 120). when it has the line under it, it means at least basically. This brings it down to two answers. The answer is B. x can be equal to or larger than 120 which means at least 120. Finally, put the dot on the second line on the right.
