Graphing linear inequalities on a number line
WebThe two rules of inequalities are: If the same quantity is added to or subtracted from both sides of an inequality, the inequality remains true. If both sides of an inequality are multiplied or divided by the same positive quantity, the inequality remains true. If we multiply or divide both sides of an inequality by the same negative number, we ... WebMar 7, 2024 · To graph linear inequalities, isolate the variable and solve the problem.
