which one do you think it is

- anonymous

B?

- anonymous

IS LOOK LIKE THE ANSWER

- anonymous

um.. i think it C

- anonymous

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

- anonymous

up*

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

- Tommynaut

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?

- anonymous

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

- anonymous

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!

- Astrophysics

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

- anonymous

then which one is it?

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|

|dw:1436416334381:dw|

- anonymous

oh, okhay i seen what i read wrong.. but awesome :)

- anonymous

I'M TRY TO UNDERSTAND THE PROBLEM

- Astrophysics

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

- Astrophysics

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

- anonymous

that's not how teacher teach them how to solve this problem. your really making it hard to understand ^^^

- Astrophysics

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

- anonymous

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

- Astrophysics

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.

- Astrophysics

< - less than
> - greater than

- anonymous

GREATER THE >

- anonymous

???

- anonymous

the answer its D

- Astrophysics

Yes

- UsukiDoll

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 .
