    Slope intercept form is y=mx+b Step 1: Isolate the term with the y variable

    You can't combine 3x and 8 because 3x has a variable and 8 doesn't

    It will be 2y=3x+8, but you still have to remove the number attached to y by dividing both sides by that number

    then you should go back to basic equations and practice that so you can get this. dont build a house of card . solid maths foundation is key.

    You need to divide both sides by 2 to remove the 2 that is with the y variable If it was a fraction, you would multiply by the denominator to cancel it out

    For the other side, simply divide both terms by 2 to get your answer.

    ok . lets say y/2=x solve for x? what operator do you need to use?

    ok if i say to you make y/2 to y what do you have to do. note that y/2 is really \[y\frac{ 1 }{ 2 }\]

    Alright sounds like people are harsh over here. The slope formula is mx+b=y So thus you need to get the equation above like it.. -3x+2y=8 First, I would add 3x to both sides. So it's like 3x+(-3x) +2y = 8 -3x, the 3x's on the left will cancel. So you will get 2y = 8-3x. So now it's almost in the mx + b =y form you have have the extra 2 in the 2y So now you need to divide both equations by 2 to eliminate the 2y. Thus it would be like... 2y/2 = 8-3x/2 or you can write it like y = 8/2-3x/2... finally the 8/2 can be reduced to 4 SO finally the answer would be... y = 4 - 3/2x

    actually time out let me fix that.. it won't be -3/2x it should be +3/2x it will actually be y = 4 + 3/2x
