If the inequality is (x-y<1), will the boundary line be included in the solution?

Answer and explanation

Correct answer: No

The inequality (x-y<1) is strict, so equality is not included. Its boundary line is x-y=1; every point on this line gives x-y=1, which is not less than 1. Therefore, the boundary line is excluded from the solution and is usually drawn as a dashed line. Exam tip: use a dashed line for < or >, and a solid line for ≤ or ≥.
