x+y<3
as slope intercept form is
x - x + y < 3 - x
...
highlight_green%28y+%3C+-x+%2B+3%29
slope is -1
graph%28200%2C100%2C-10%2C10%2C-10%2C10%2Cy%3C-x%2B3%29
...
x-y > 4 or is that x-y > -4 ?
x-y > 4 is x - y + y - 4 > 4 - 4 + y
highlight_green%28y+%3C+x-4%29
graph%28200%2C100%2C-10%2C10%2C-10%2C10%2Cy%3Cx-4%29
...
if it is x-y > -4, then
x - y + y +4 > -4 + 4 + y
highlight_green%28y+%3C+x+%2B+4%29
...
graph%28300%2C200%2C-10%2C10%2C-10%2C10%2Cy%3Cx%2B4%29
...
Either way on this last one, slope is 1
