Question

Which of the following inequalities matches the graph?

Answer 1

graph?

Answer 2

A)x< 2
B) Y> 2
C) Y< 2
D) X>2

Answer 3

@nerlineg

Answer 4

which one do you think it is

Answer 5

B?

Answer 6

IS LOOK LIKE THE ANSWER

Answer 7

um.. i think it C

Answer 8

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

Answer 9

up*

Answer 10

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

Answer 11

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?

Answer 12

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

Answer 13

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!

Answer 14

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

Answer 15

then which one is it?

Answer 16

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?

Answer 17

@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.
