And if we're still unsatisfied, we can have yet another. Sometimes, we might want to limit the possibilities even further, so we introduce yet another inequality and demand that the variable satisfies both of them. Now that we know how to graph inequalities on a number, what do you suspect our next move should be?Īs mentioned in the first section, linear inequalities give us a rough idea of what values our variable admits. Therefore, they mark sets of all numbers from minus infinity to some value (for and ≥). As such, the linear inequality plots also are infinite (but in one direction). Remember that the number line graph is a representation of an axis that is infinite in both directions. Here, we use the variant in point 3 above since it's what Omni's graphing inequalities on a number line calculator uses.
