Solving a one step inequality

The video tutorial explains how to solve the inequality n + 2 ≤ 4 and represent the solution on a graph. It begins by treating the inequality like an equation, using inverse operations to isolate the variable. The solution, n ≤ 2, is then interpreted, and a number line graph is used to visually represent all possible solutions, including decimals and fractions less than 2.

Describe how you would shade the graph to indicate the solution set for n ≤ 2.

What does it mean when we say that there are infinite solutions to the inequality?
