Answer
$y\geq3x+3$
$y< -x-2$
Work Step by Step
(-1,0) and (0,3)
$m = (3-0)/(0--1)$
$m = 3/1 = 3$
$y=mx+b$
$3 = 3*0 + b$
$3 = 0 + b$
$3 = b$
$y=3x+3$
(0,0) is not part of the solution, so $y\geq3x+3$ is the formula
(-2,0) and (0, -2)
$m = (0--2)/(-2-0)$
$m = 2/-2 = -1$
$y = mx+b$
$0 = -1*-2 +b$
$0 = 2 + b$
$0-2 = 2+b-2$
$-2 = b$
$y= -x-2$
(0,0) is not part of the solution, so $y< -x-2$ is the formula
