Ok, i need help identifying and graphing linear equations and putting them in standard form. So can anyone give me a couple of answers and tell me how you got them???!!Please
the directions say to determine whether each equation is a linear equation,if so write the equation in standard form
1) 3x=5y
2) 6xy + 3x =4
3) 7y=2x + 5x
4)3/x +4/y =2
5) 7n - 8m =4 - 2m
Thank you to anyone who can help me!!

Hi,
Y= mx +c is a stand equation.
Conver all of them in above format
ex: 3x=5y
y=3x/5
any given values of 'x', you can find y values
ex: x = 0 means y=3*0/5 =0
x=1 means y=3*1/5 = 3/5
x=2 means y= 6/5
You can draw these (x,y) points in a graph.
hope this helps.

solve for 1 variable then graph:
3x=5y
y = 3x/5
y = 3/5*x
this is a line intersecting 0 rising to the right.
6xy + 3x =4
6xy = 4 - 3x
y = (4 - 3x)/6x
y = 1/6 * x * (4 - 3 * x)
This is a curve intersecting 0
etc.

standard form isnt y=mx+b (thats slope intercept form) standard form is Ax+By=C

1) y=(3/5)*x
2) non-linear
3) y=x
4) non-linear
5) non-linear

Yes, I'm sure there are many people who are good in Algebra; I used to be, but not anymore. :,(
I'll take my 10 points, now, please and thank you! ;)
