## Esmy 3 years ago Graph the linear inequality. x + 2y = 5 I don't have a graphing calculator -_-

1. AravindG

ya this one is an easy task , let me guide you first divide the whole equation by 5

2. AravindG

@Esmy what did you get?

3. Esmy

x - 2y=5 x=2y+5 -3x+2y=7 2y=3x+7 3x=2y-7 2y-7 x-------- 3 2y=5= 2y-7 ------ 3

D: ?

5. Esmy

but I don't have a graphing calculator so I don't know how it looks what part is shaded?

6. amorfide

okay rearrange this equation to get 2y= 2y=-x+5 then you will sub in x values x -2 -1 0 1 2 3 2y 7 6 5 4 3 2 so to get y you divide all x values by 2 this gives x -1 -1/2 0 1/2 1 3/2 y 7/2 3 5/2 2 3/2 1

7. Esmy

Can you draw how it would look :/ sry

8. amorfide

|dw:1348393679154:dw| something similar to this i believe

9. amorfide

it should go through all points but i find it hard to draw on pc

10. lambchamps

you should have test points to know where the shaded area is.

11. Esmy

|dw:1348393961736:dw| Yeah it looks like that and then its shaded right?

12. amorfide

she give me an equal sign not an inequality

13. Esmy

my picture is ugly but you get what I mean lol

15. sudharsa

this would be i think so

16. Esmy

17. Esmy

Like that one right :D

18. lambchamps

question, can someone remind me how to know the shaded part?

19. Esmy

The dark grey is the shaded :o

20. AravindG

@Esmy did you try what i said?

21. lambchamps

how did you get it?

22. Esmy

the picture ? yeah I did I tired it...

23. AravindG

nope did u try dividing whole equation by y 5?

24. sudharsa

aravind that is good idea pls get new idea pls

25. Esmy

I got x= -6 and y= -5.5

26. Esmy

but the pic I posted is most likely how the it should look...
