    ITS a vertical line going uo in down Y is 0 so it has to be less

    Please do not give the answer directly @nerlineg help guide them, and ask them questions rather than just saying the answer

    My bad! Again, my mistake. I meant to say: y = b (where b is some constant, like 5) is always a horizontal line. x = a (where a is some constant, like 5) is always a vertical line. So do we have a horizontal or vertical line?

    i did not give her the answer. i ask her which she thought it was. and she said B.. soo.... I'd basically corrected her and gave her why i thought it was C and not B so.... THANKS :) @Astrophysics

    so.. I know what I am doing id ask her which one she thought it was, she said B and i told her their is a better answer and why,,, so re-read before you comment!

    Well you're missing the point and also you gave the wrong answer.

    So @EmilyF03, do we have a horizontal or vertical line? After you've decided, pick any point in the region and substitute it into the equations you're left with. Of course, you'll only be able to sub in the x or y value of that point, depending on what equations you're subbing in to. Let's say you've narrowed it down to x < 2 and x > 2. Pick any point in the region, maybe the point (8,0). That's 8 across to the right and 0 up/down. Can you see how that point is in the region? Now, considering neither of your equations have a y in them, you can't sub in the y value anywhere, but you can sub in the x value. For x < 2, sub in x = 8. Is the equality true? For x > 2, sub in x = 8. Is the equality true?

    @EmilyF03 When you graph equation as such, thing of linear equations first, what is y = 2? and what is x = 2? y = 2, implies (0,2) right, so we do the following, which gives us the horizontal line. Similarly we can say x = 2, is (2,0) which gives us a vertical line. Now we just apply what we know of the signs, see if you can figure that out.|dw:1436416152024:dw|

    What I should really say is, y = 2, implies every point on the graph where there's (x,2)

    So for the line you have (1,2), (2,2)...etc, and similarly for x = 2

    At this point you just need to know your inequalities what > and < means

    SO FOR ME THE ANSWER IS A? X<2 ? IM RIGHT?

    Close, but not quite x<2 think of it this way...this means x is anything less than 2, |dw:1436416667745:dw| this is what x<2 means, the left of the graph, notice how we get into negative numbers on that side.

    yes because you were given a vertical line at 2 which means that x = 2. Since your region was shaded to the right that means that all values greater than 2 .
