Question

Which of the graphs represents the inequality y – 2x < 3?

Answer 1

DO you know how to draw a graph for the line y -2x=3

Answer 2

I dont see how too get the answer though?? Its diving me crazy cause i have tried everythang i no to do.

Answer 3

i asked you can you draw the line y-2x=3 in a graph?

Answer 4

no?

Answer 5

ok......i will tell you a simple way of doing so

Answer 6

Okay.

Answer 7

take any value of x. lets say x=1
what is the value of y now

Answer 8

1

Answer 9

Nope...check again

Answer 10

-2 i think im sorry i suck at this..

Answer 11

y -2x =3
I put x=1
so, y -2(1) =3 or y -2 =3
so y =??

Answer 12

no you are good......just think a bit

Answer 13

you know when two sides are equal you can add and subtract equal numbers from it and they still will remain equal.
so if y-2 =3
I can add 2 on both sides and they still remain equal

Answer 14

Can you get y now?

Answer 15

So it would stay at 2 so then it would be
y=2+5 ?

Answer 16

no no no

Answer 17

:(

Answer 18

y-2 =3
so i add 2 on both sides
y-2+2 =3+2
y=5

Answer 19

Oh i get it cause of corse the 2 would cancel out and then it would be left at 3+2 which is 5. so then hoe would you be able to graph it?

Answer 20

Now since x=1 and y=5 satisfy the equation
(1,5) is a point on the graph

Answer 21

* sorry i ment how?

Answer 22

Yes. But there has too be another point to correct?

Answer 23

Yes exactly! so i take another value of x. lets say x=2 and find the value of y again

Answer 24

So then it would be
y=-2x=2
+2 +2
y=-1x-2?

Answer 25

nope
we do it this way: y-2x =3
I take x =2
so, y - 2*2 =3
or y-4=3
Now can you find y??

Answer 26

y=-1

Answer 27

Nope again
y -4 =3
Now as I told you before when two sides are equal I can add or subtract any numbers from both sides and they will still remain equal. So I add 4 on both sides
y-4+4 = 3+4
y =7

Answer 28

That would be rite i aded the wrong side together. Thats were i was wrong. I add the oppisite side togeter and thats how im gettin the wrong answer.

Answer 29

You just have to work on your calculations a bit :D

Answer 30

Well thanks so much dollface yo was a BIG help as you can see i was lost!!

Answer 31

Ok so we have two points that we know satisfy the equation
(1,5) and (2,7)
Can you now find a line on the graph that passes through these points?

Answer 32

Yes.

Answer 33

K now this line is y-2x =3

Answer 34

and this line divides the whole plane into two parts

Answer 35

One part is y-2x >3
and the other part is y-2x<3

Answer 36

Yes..

Answer 37

Yes no i have the correct answer and finally passed the quiz!

Answer 38

Oh great!

Answer 39

Thanks so much!!!!

Answer 40

You are welcome :)
