Work Step by Step

The inequality $x-y \geq -1$ is graphed with a solid border line $x-y=-1$ which for x=$0$, y=1. and for $y=0,\ x=-1$. Draw a solid line through ($0,1)$ and $(-1,0).$ Test point: (0,0).$ \quad $Is $0-0 \geq -1?$ Yes, shade the region containing (0,0) The inequality $5x-2y \leq 10$ is graphed with a solid border line $5x-2y = 10$ which for $x$=$0$, y=$-5,$ and for $y=0,\ x=2$. Draw a solid line through ($0,-5)$ and $(2,0).$ Test point: (0,0).$ \quad $Is $5(0)-2(0) \leq 10?$ Yes, shade the region containing (0,0) The solution set for this UNION is the region with EITHER shading.
