all you really need to do is plug in each point to 

2x+6y>-12

for example, the point (-8,-3)

-16+-18>-12

that is not a valid point, as -34 is not greater than -12

anonymous · Answer

so you do 2x* -8 to get -16 and 6*-3 to get 6??

dtan5457 · Answer

dtan5457 · Answer

well i mean it's pretty much the exact same thing

y<=3x-6

checking for point 7,14

14<=3(7)-6

14 is less than 15, so that point is valid
