To determine all the solutions to the linear inequality , one must envision any number strictly greater than , such as , , or even . On a number line, this solution set is visualized by putting an open parenthesis at the boundary point —demonstrating that exactly is excluded—and shading every number to its right. This region extends infinitely upwards, so using interval notation, the solution is written as . The symbol signifies infinity, indicating that the interval continues endlessly without a maximum upper bound.
