## SerenitysMommy 3 years ago Which of the graphs below represent the graphical solution to the following system of equations? 4x + y = 5 3x – 7y = 27

2. SerenitysMommy

Whats the points ?

3. SerenitysMommy

And non of my graphs show close to looking like that =/

4. amistre64

itd be better if we could see your graphs since this thing isnt actually a precise rendition :)

6. amistre64

that one might work :)

7. SerenitysMommy

I will try and drawl my answer choices

8. JoãoVitorMC

you need the point of intersection?

9. amistre64

10. SerenitysMommy

I have a answer choice that shows that!!! How'd you get the answer

11. JoãoVitorMC

so you need the intersection, i will calc and show here

12. amistre64

you draw the line and see where they cross ....

13. SerenitysMommy

How do you know what line to drawl?

14. amistre64

the x and y values are from the equations that are given

15. SerenitysMommy

? Explain? Im looking at the numbers and not getting how you draw them

16. amistre64

4x + y = 5 when x=0. y=? (0,y) 4(0) + y = 5 0 + y = 5 y = 5 (0,5) when y = 0 x = ? (x,0) 4x + y = 5 4x + 0 = 5 4x = 5 x = 5/4 (5/4 , 0) plot the points, and since they are lines ... conect the dots

17. amistre64

then work the other line in the same way

18. SerenitysMommy

Ohhhhhhh.

19. amistre64

any 2 points will work, just have to find them. x=0 the y=0 tends to be the easiest way tho

20. JoãoVitorMC

\[y = -4x +5\]\[3x -7y=27\]\[3x -7(-4x +5)=27\]\[x =2\]\[y =-4(2)+5\]\[y = \]\[P(2, -3)\]
