Need help with Graphing Systems of Linear Equations 1. Solve the system 2x + 2y = -6 and 3x - 2y = 11 by using graph paper or graphing technology. What is the solution to the system? 2. Solve the system y = 3x + 2 and 3y = 9x + 6 by using graph paper or graphing technology. What is the solution to the system?

hel man im in this stuff dont ask me i ask u lol

OpenStudy (destinymasha):

y = 3x + 2 and 3y = 9x + 6 , what we need here is to find the values of x and y

OpenStudy (destinymasha):

do you have any options?

OpenStudy (axel.caballero):

For the first one its (-1, -7) (1, -4) (2, -1) (3, -2) and the 2nd one is No Solutions Infinite Solutions (3, 2) (9, 2)

OpenStudy (axel.caballero):

@Destinymasha

OpenStudy (destinymasha):

i believe its infinite solutions, Dividing the 2nd equation by 3 yields y=3x+2, which is the same as the first....

OpenStudy (destinymasha):

9x + 6 divided by 3 = 3x +2

OpenStudy (axel.caballero):

So the second one you think is infinite solutions? I graphed the second one and both were the same thing. And how about the first one? how would you do that one?

OpenStudy (destinymasha):

yes

OpenStudy (destinymasha):

hold on

OpenStudy (axel.caballero):

okay

OpenStudy (destinymasha):

sorry its taking me so long, this one is a little tricky for me

OpenStudy (destinymasha):

my guess would be (3, -2)

http://www.wolframalpha.com/input/?i=solve+2x+%2B+2y+%3D+-6+and+3x+-+2y+%3D+11+ For the second, the two functions are the same, so we have infinite of solutions
