@Mathematics

Answer 1

(5,1)

Answer 2

(–2, 5)
(–2, –5)
(2, –5)
(2, 5)

Answer 3

solve one for x and solve the other for y

Answer 4

lol, that doesn't help me at allllll.

Answer 5

haha so do you know how to solve an equation such as 2x-y=7?

Answer 6

no, lol.

Answer 7

i don't know how to do that either.

Answer 8

just plug in those numbers...

Answer 9

but that isn't mathematical at all mahone

Answer 10

which means what?

Answer 11

The question says "Choose the point which is a solution to the system of inequalities" not "Find the domain for which the following system of equations holds."

Answer 12

by defining the domains of the inequality you can find what values will work.

Answer 13

Why do that if she was given four values to test?

Answer 14

Isn't that the smartest thing to do?

Answer 15

To define all answers that it could be and picking out the one that is correct would personally to me, would help understand the concept rather than plugging in the points, but if you want to go ahead and plug them right into the equation, go ahead

Answer 16

Okay, you have an infinite amount of points to test. Go ahead and become an expert code monkey.

Answer 17

I've never had a teacher where the question is here are some points plug into an equation.

Answer 18

i don't know how to do anything you guys are talking about.

Answer 19

and mahone i'm not testing infinite amounts of points. I'm given only 4 pts to test but if the question said *which is what my teacher's questions looked like*, "Find all values that would be a solution set of the system of equations"

Answer 20

the answer is 2,-5

Answer 21

well i guessed, &ended up getting it wrong.

Answer 22

but thanks.

Answer 23

well that sucks =[

Answer 24

eh, it's okay. i'm used to getting stuff wrong.
