Help Solving Systems of Equations by Graphing

[zespheley]

I am given two sets of equations for each problem i messed up on them so please help me...


its not the graphing thats getting to me its solving these where 'Y' is isolated.
basically slope int. form like so y=mx+b


3x-7y=6
x+2y=11

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

^^this one I got 1x+5=y and 1x-5=y but i'm not so sure.

1/4x+2y=5
2x-y=6



I need help ASAP...I would appreciate it.

to get in the form of y = mx+b, solve for y:

x+2y=11

2y = -x + 11
y = (-x + 11)/2
y = - (1/2)x + 11/2
