Remember that a parallel line will have the same slope!
OpenStudy (steve816):
First, you must get the equation into y=mx+b form. Do you think you can do that?
OpenStudy (bluemoon1):
I have no idea how to do this
OpenStudy (bluemoon1):
I don't know how so if you could explain that would be great lol

Let's take the first one as an example. This is what you would do:
x - 4y = 4
-4y = -x + 4
y = x/4 -1
OpenStudy (steve816):
\[\large y=\frac{ 1 }{ 4}x - 1\]
OpenStudy (steve816):
Therefore, the slope would be 1/4
OpenStudy (bluemoon1):
How about the second one?
OpenStudy (steve816):
Try number 2 on your own!|dw:1478735338486:dw|

Okay so I understand number 1 because you are solving for y, right?
OpenStudy (steve816):
You are also solving for y for number 2 too!
OpenStudy (bluemoon1):
2x=-5y
x= -5/2?

5y=-2x\[y=-\frac{ 2 }{ 5 }x\]
m=?
OpenStudy (bluemoon1):
I don't know how to solve for m
OpenStudy (sshayer):
y=mx+c
here c=0
m=?
OpenStudy (bluemoon1):
M=0?
OpenStudy (bluemoon1):
Omg I'm confused

\[y=-\frac{ 2 }{ 5 }x,y=mx,m=-\frac{ 2 }{ 5 }\]
OpenStudy (bluemoon1):
Oh so that's the answer?
OpenStudy (sshayer):
yes
