Identify the vertices of the solution region of the system of linear inequalities. (Order your answers from smallest to largest x, then from smallest to largest y.)

x ≥ −2
x ≤ 3
y ≤ 5
y ≥ x

(x, y) =
(x, y) =
(x, y) =
(x, y) =

Tried several times, just can't get this - Help!

The vertices involving y>=x are clearly

(-2,-2) and (3,3)

The rest you can surely find...
