## Gabylovesyou 2 years ago Choose the correct graph of the given system of equations. y − 2x = −1 x + 3y = 4

1. Gabylovesyou

2. Gabylovesyou

D.None of the above

3. Gabylovesyou

@blondie16

4. blondie16

solve for y

5. Gabylovesyou

y − 2x = −1 i get: y = 2x -1

6. blondie16

right :) then graph it

7. Gabylovesyou

i dont see it in those graphs..... ^^

8. Gabylovesyou

wait..

9. blondie16

wait?

10. Gabylovesyou

how do i graph it?

11. blondie16

the y-int. then the slope is up 2 over 1 or down 2 over 1

12. Gabylovesyou

A?

13. Gabylovesyou

@blondie16

14. blondie16

no it is not a

15. Gabylovesyou

???????

16. blondie16

graph it and find it it would be B

17. Gabylovesyou

no its not B

18. blondie16

how?

19. Gabylovesyou

yes it is nevermind... i get a positive slope for the first one and a negative slope for the other one........

20. blondie16

lol

21. Gabylovesyou

im so confusing lol

22. blondie16

xD

23. Gabylovesyou

im correct right? lmfao..

26. Gabylovesyou

I haven't done this in two years D: @ash2326 help her? :D Please? haha

28. Gabylovesyou

lol :) thanks

No problem haha

30. ash2326

@Gabylovesyou Can you solve simultaneous linear equations?

31. Gabylovesyou

O.o no lol .......

32. Gabylovesyou

@ash2326 I did it already.... can u check my answer?? I got B?

33. ash2326

How did you solve this?

34. Gabylovesyou

solved for y and then i graphed both of them ..

35. ash2326

How did you graph? Did you use a paper?

36. Gabylovesyou

no......... i used the comp..

37. ash2326

for solving y also?

38. Gabylovesyou

no... for solving y i used paper lol

39. Gabylovesyou

@ash2326

40. Gabylovesyou

Am i correct? is it B ?

41. ash2326

Yes, you are right. But I feel that you could have used another method for solving for x and y You can find y in terms of x from both the equations and compare them to find the value of x and then use x value to find y. The value you'll get for x and y, will be the point where the lines intersect.

oh. lol :p ok ..
