If there is a sign in the original inequality, then the answer is indeed

However, if there is NO underline under the inequality sign, and you have a sign only, then the answer is

Graphing

Step 1) Draw a number line. Be sure to include x = 4 on the number line

Step 2) If the answer is plot a closed circle at x = 4. If the answer is plot an open circle at x = 4.

Step 3) we have a "less than" as part of the answer, so we shade to the left of the circle (whether it's open or closed)
