Which side is shaded for \(y\geq x-1\)?

Correct answer: above the line including the line

In \(y\geq x-1\), the value of \(y\) must be equal to or greater than the value on the line \(y=x-1\). Hence, the half-plane above the line is shaded. Since \(\geq\) includes equality, the boundary line is drawn solid. The region below the line represents \(y<x-1\), so it is not correct. Exam tip: for \(y\geq\) or \(y>\), generally choose the region above the line.
