Graphing inequalities on number line rules
WebOct 6, 2024 · Two common ways of expressing solutions to an inequality are by graphing them on a number line and using interval notation. To express the solution graphically, draw a number line and shade in all the values that are solutions to the inequality. Interval notation is textual and uses specific notation as follows: Figure 2.7.1 WebInequality Symbols: you must know and recognize these. < “L” LESS than > Greater than ≤ Less than OR equal to (2 symbols together) ≥ Greater than OR equal to (2 symbols …
