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

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

    So that would be Part A?

    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?

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

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

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

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

    They just want something that isnt staying the same.

    Thus a parallel line?

    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

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

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