^^ screenshot of problem

Answer 2

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

Answer 3

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

Answer 4

well it's not 6 but, your are substituting correctly

Answer 5

didnt mean 6 sorry lol thanks

Answer 6

Np, do you know how to do the rest? good from here?

Answer 8

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

Answer 9

ahh i see you plug it in ok thanks
