-7=1/2y I have moved the -7 over to the other side of the = and made it positive, but what do I do next?
Hmm. what was the original problem asking you to do or find?
the slope and the y intercept of the line

What information were you given?
-7=1/2y
Hmm.. ok. That's really weird. They want you to find the slope and y-intercept given that the line satisfies -7 = (1/2) y?
yes
is it -7 = (1/2) * y or -7 = 1/(2y)?
-7=1/2y that is all it gives. no ()
Is the y in the numerator or denominator?
it is a fraction with y beside the line
i really appreciate you helping me
oh ok
So that means that y is being multiplied by (1/2), one-half
yes
Ok, that's the same as y being in the numerator, or the top, of the fraction, but it's different than y being in the bottom of the fraction
OK, so how do I clear the fraction or do I?
Anyways, we want to solve for y by itself to get the equation of the line in “point-slope form” Solving for y by itself, we see that y = -14, after multiplying both sides by 2.
why by 2 what happened to the fraction
sorry I'm not good with this
Oh ok.
So suppose I said, I have some money in my bank account, and if I gave you half of that, you would have 10 dollars. So how much do I have right now?
5
Not quite.
I didn't give you the money yet.
20
oh
Yeah.
So if I said I have money in my account. If I gave you half, you would have 1000. So how much money do I have?
2000
Exactly
You just solved "(1/2)* y = 1000"
To solve (1/2)*y = -7 for y, it's the same idea
oh ok
if I have +7 and divide by 2?
No, when we solved for y, what did you do to the 1000? You multiplied by 2.
So if (1/2) * y = -7, then to solve for y, we should multiply -7 by 2
makes it -7/2
If I moved the -7 to the other side of the = sign don't that make it +
Well, when we multiply 7 by 2, we get 14. So multiplying -7 by 2 gives us -14.
you lost me
No, that's only if you're adding the -7 to the other side.
I thought that is what I had to do to get y=mx + B
Oh, I can see why you're confused.
If A = B, then B = A.
So if -7 = (1/2) * y, then (1/2) * y = -7.
We didn't "move 7 to the other side of the equation" by adding it, we just rewrote the equation with the y on the left side and the 7 on the right.
?
I thought when you moved it to the other side of the = you had to add or subtract it?
I have to go soon. It looks like you need extra help. I don't think this site is good for you if you need more help one-on-one tutoring.
ok thanks for trying
But does it make sense to you that if A = B then B = A?
yes
What about if A = -7, then -7 = A?
ok
hello every1
cm on chat box
good luck karebear
thanks
