Question

Which solution set is graphed on the number line?
A number line going from negative 4 to positive 4. An open circle is at 1. Everything to the left is shaded.
x greater-than-or-equal-to 1
x greater-than 1 and one-third
x less-than 1

x < 1

The open circle at 1 means 1 is not included, and the shading to the left of 1 indicates all numbers less than 1.
