@igreen plz help me

Answer 5

Part A:

You could say:

I can graph the equation to find all the solutions to it.

(Btw, remember me? I'm greenlegodude57, I just created a new account for a better username)

Answer 6

oh ok, and holy crap whats up dude :D:D

Answer 7

ohok so all i would need to say is i can graph the question to find my solution ??

Answer 8

Lol

Answer 9

To find ALL of the solutions. That's for Part A.

Answer 10

oh ok thx bro can u help me with b and c lol

Answer 11

Yep

Answer 12

For Part B:

Just say I looked on my graph and got these solutions: (0, 2),(1,11),(2, 20)

Answer 13

jw how did u get those corresponds

Answer 14

sorry i meant integers

Answer 15

Part A: I'm assuming you're done with this. Your 9x - y = -2 becomes y=9x+2.

Part B: all you have to do here is to choose three arbitrary x-values and to substitute them into y=9x+2, one at a time. You'll get three y-values. For example, if you choose x=2, then y=9(2)+2=18+2=20, and the corresponding point is (2,20). Find two more points in the same way (two more points that lie on this line).

Part C: Before I discuss this, I'd like for you to look up the word "inconsistent" as it applies to algebraic equations. Perhqps look up "inconsistent systems of linear equations." Obviously we have to understand this terminology before we can come up with a valid answer to the question posed in Part C.
