Where is the solution region of the inequality \(y<-2\) located in the \(xy\)-plane?

Answer and explanation

Correct answer: Below the line \(y=-2\)

In \(y<-2\), the value of \(y\) must be less than \(-2\). The boundary \(y=-2\) is a horizontal line, so all points below it satisfy the inequality. Because the inequality is strict, the boundary line itself is not included and is usually drawn dashed. Exam tip: when \(y\) is compared with a constant, draw a horizontal boundary and choose the region above or below it.
