Question

Can someone help - Which point lies in the solution set for the following system of inequalities?

2x + y > 8
x − y < 2
I don't know how to do this one.

Answer 1

you take the given points and test them in the system to see whats true

Answer 2

if you need to find one point, its about the same as usual when they have = signs

Answer 3

I think it's (3,4) - but I don't know.

Answer 4

is 3-4 < 2 ?

Answer 5

No so is it (6,1)?

Answer 6

what is 3-4 equal?

Answer 7

3 - 4 = -1

Answer 8

good, so is -1 < 2 ?

Answer 9

Yes, omg I had a brain fart for a second.

Answer 10

then lets test the second eq

2(3) + 4 > 8 is this true?

Answer 11

yes

Answer 12

then since both are true with 3,4 that is a solution

Answer 13

Thank you :)
