Quick Algebra Question! 10/10 and major rep!

[FatWhore]

So, my algebra teacher sucks. We have a final tomorrow and she didn't teach us half the shit that's on it. Basically were solving systems of equations. I have a equation, 2x - y = 1. Then to make it into slope intercept form, i subtract 2x from both sides, making it -y= -2x + 1. Normally that would be graphed m= -2/1 and b=1, but what if the y is negative? Does that change anything?

Spark Notes: what happens if the y is negative in y=mx+b?

flip dat shit up side down

 

[ikindalikeskiing]

Multiply it all by -1

 

[2_fadez]

fuck i dont know

enter in points in a graph and findout

be curious. you'll learn more

 

[crazysincethe80s]

Flip it like yay

 

[penguin_steeze]

divide everything by -1 so that y will be positive

 

[rankstank]

-y=-2x+1 is the same as y=2x-1

 

[EvanWalz]

this man, right here, is correct

 

[FatWhore]

thanks! 10/10

 

[The_Beekeeper]

Just change the signs of every term, i.e. multiply by -1.

people have the hardest time with the number 1

Math is pretty cool if you have a good teacher.

 

[manutdsaol]

This yo the y has to be positive

"she didn't teach us" is not a valid excuse. Pay attention and quit being an asshat in class, it'll pay off.

She had a baby and was out, the sub hired was a lang. arts teacher...

 

[TimRiley]

-y= -2x + 1 muliply through by -1. y= -1(-2x +1) final answer to graph slope y=2x -1

Sidebar - Are you the guy who got mad at me for doing the callout at tyrol?

 

[Bodhisattva_]

Lolololll ok that is an acceptable excuse.

 

[Flacko]

i thought that meant the y intecept was negetive on the y axis, so it would be below the x axis

 

[Casper.]

Correct

http://www.khanacademy.org/ haven't used it personally but have heard good things about it

 

[Lucas]

Haha oh shit this happend to my friends and there class average on tests have been at like 60% for the last month

 

[mynamegus]

if you multiply or divide by -1 (ive been shown both) then you will go from -y=-2x+1 ->y=2x-1.

This was one of the dumbest things I have read regarding math in a long time.
