Example: Solving and Graphing
The linear inequality is solved using the Multiplication Property of Inequality. First, isolate the variable by multiplying both sides by the reciprocal of the coefficient, which is . Because is a positive number, the inequality sign is unchanged, returning the true statement . To make graphing more intuitive, this can be rewritten with the variable on the left as . The solution is then graphed on a number line with a left parenthesis at and shaded to the right. In interval notation, this represents the interval .
