Which side of the number line should be shaded according to the inequality?
Inequality: x<7
Graph:
This solution set can be written as an inequality. x<7 To graph this inequality, we place an open circle at 7 on a number line. Since x is less than 7, the solution set includes all numbers that are below 7. Therefore, we should shade everything to the left of the open circle.
