Which of the regions U, V, X, Y, Z shown satisfies the inequalities $0 < y < 2$ , $y < 3 + x$ , $x < 0$ ?

Worked solution (try it first)

$0 < y < 2$ puts the region between the $x$ -axis and the line $y = 2$ .
That rules out U, V and X.
$x < 0$ puts it to the left of the $y$ -axis, and both Y and Z are there.
$y < 3 + x$ puts it below, that is to the right of, the slanted line.
Only Z is on that side, so option E.
