To find a solution to a linear inequality on the coordinate plane, first find the equation as if it were a line. If the inequality says y < that line, then shade below that line for the solution. If the inequality says y > that line, then shade above that line for the solution.
Good to know! If the inequality is “less than or equal to” or “greater than or equal to” then the line (and points on it) is included in the solution.
