## anonymous one year ago An equation is shown below: 9x - y = -2 Part A: Explain how you will show all of the solutions that satisfy this equation. (4 points) Part B: Determine three different solutions for this equation. (4 points) Part C: Write an equation that can be paired with the given equation in order to form a system of equations that is inconsistent. (2 points)

The slope is 9 and the y-intercept is 2.

4. anonymous

Well, the domain and range for this equation are both -infinity to infinity. Which means there's an infinite number of solutions.

5. anonymous

So that would be Part A?

6. anonymous

I suppose so. I mean, there's no way for you to give all of the infinite answers. I suppose you could prove why the domain and range are infinite, but i can't think of anything else.

As for part B, just select three numbers for the x and plug them in and get the y that correlates. Generally you just do -1, 0, and 1 as the numbers for x.

I'm not sure what they want for Part C, do you have any clue?

10. anonymous

And put -1, 0, and 1 in for the x of \[y=9x+2\]

11. anonymous

Oh ok thanks! & for part C they want you to write a similar equation to form a systemof equations that is inconsistent.

12. anonymous

What do they mean by inconsistent? It's been so long since I've dealt with some of these terms.

13. anonymous

Ohh, just looked it up on purple math. So basically they want a parallel line right?

14. anonymous

They just want something that isnt staying the same.

15. anonymous

"Inconsistent system: no solution and no intersection point"

16. anonymous

Thus a parallel line?

17. anonymous

Well anyways. To get a parallel line, just keep the slope the same and change the y-intercept. \[y=9x+b\] with b being anything but 2

18. anonymous

So for example just write y= 9x+3 ?

19. anonymous

Yeah, that would work.

20. anonymous

And you might wanna ask to confirm what they're looking for for Part A.

21. anonymous

Alright thanks for everything!! Do you thing you could help me with one more question?

22. anonymous

No problem. I'd love to help, but I have some other stuff i gotta do =(
