You can modify the first equation by subtracting $x$ $x$ from both sides

$y \leq 5 - x$ $y<=5-x$
This is a straight line and we need everything below AND including it.
graph{5-x [-4.875, 15.125, -1.36, 8.64]}

$y > 2$ $y>2$
This is a straight horizontal line at $y = 2$ $y=2$ We want everything above it, NOT including the line itself.
