SOLVING/GRAPHING INEQUALITIES
One way to solve a linear inequality or a system of linear inequalities is through the Graphical Method, where boundary lines are plotted and the regions that satisfy the single inequality or the system of inequalities are shaded.
“Wait. Graphical? Couldn’t we just use Desmos then?” “Oh yeah! Des’ Meso!”
