Don't you want to try this one now? You solve it and so will I and we can see if we agree.

y-1=6 1/2?
OpenStudy (anonymous):
Oh wait
OpenStudy (mertsj):
\[\frac{1}{2}=\frac{y-1}{5+1}\]
OpenStudy (anonymous):
y-3=6

\[\frac{1}{2}=\frac{y-1}{6}\]
OpenStudy (anonymous):
*y-1=6
OpenStudy (anonymous):
y=4?
OpenStudy (mertsj):
Yes. y = 4. Way to go!!!

Oh very. Sarcasm intended haha
OpenStudy (mertsj):
Well, just be thankful that God gave you a good brain so that you can learn. Pity those unfortunate people who can't.

What if in this case, you find x and its -3-7/4-x and the slope is -1?
OpenStudy (anonymous):
Yes, praise the Lord. :P
OpenStudy (mertsj):
i would cross multiply. I think that might be easiest.

x=6?
OpenStudy (mertsj):
\[\frac{-10}{4-x}=\frac{-1}{1}\]
OpenStudy (mertsj):
I got -6
OpenStudy (anonymous):
I'll try it again
OpenStudy (mertsj):
-3-7=-10

And slope is -1 which is -1 over 1 or 1 over -1
OpenStudy (mertsj):
When you cross multiply you get -4+x=-10
OpenStudy (anonymous):
Okay so the -1 has to multiplied like this?: -1(-4-x)
OpenStudy (mertsj):
exactly.
OpenStudy (mertsj):
No. it's -1(4-x)
