you forgot the negative 5y = -3x + 9
Bacon
  • Bacon
Sosa that was a bit confusing though

Oh my. Not only DON'T give answers, but for God's sake, don't give WRONG answers, as both of the above answerers did.
Bacon
  • Bacon
Oh?

Debbie can you help then please?
DebbieG

@Bacon , just solve the equation for y. @AlmightySosa300 was close, but just forgot that you have to SUBTRACT the 3x from both sides, so it becomes negative on the RHS.

sorry guyz...i thought it was asked in intercept form only
DebbieG
  • DebbieG
3x+5y=9 Subtract 3x from both sides. Then divide both sides by the coefficient on y (the 5). That will isolate y, once you have y=mx + b, that's your slope-intercept form.

  • anonymous
3x+ 5y=9 we will have to make in the form of y=mx+c that is 5y=9-3x y=(9-3x)/5 y = (9/5)+(-3/5)x y=c+mx
Bacon
  • Bacon
so erm would the b be a fraction then?
Bacon
  • Bacon
or c in viveks case
DebbieG
  • DebbieG
Yes, you'll get a fraction for both the y-intercept and the slope. That's ok, some lines are just like that. :)

Btw, your username and pic are cracking me up.

lol thanks
Bacon

:D
Bacon
  • Bacon
so would these be the steps then? 3x+5y=9 5y=3x+9 5y=9?
Bacon
  • Bacon
and then y=9/5
DebbieG
  • DebbieG
Woah.... first off, you did not SUBTRACT the 3x on the right. You cant SUBTRACT it from the left but ADD IT to the right. :) So the sign is wrong. But more importantly.... WHERE DID IT GO?? It just disappeared between step 2 and step 3. It's part of the equation for the line!

y is not = a constant here, y = a function of x. The x term has to be there.
Bacon
  • Bacon
Debbie can you please just write out how you would do it so i can see where i went wrong please?
DebbieG
  • DebbieG
Well, I explained exactly where you went wrong. But what I WILL do is a DIFFERENT problem that is of the same type, as an example. So let's solve 5x+2y=11 for slope intercept form, which as I said, just means to "solve for y". That will give me y=mx+b 5x+2y=11 I need the y term alone, so I will SUBTRACT the term with the x from both sides: 2y=-5x+11 Now I'm almost there, just need to divide both sides by 2 (which you can, alternatively, consider as multiplying by 1/2, since that's the very same thing). Just remember that on the right side, I must DISTRIBUTE to both terms, e.g.: (1/2)*(2y)=(-5x+11)*(1/2) Which gives me: y=(-5/2)x+11/2 Slope = m = -5/2 Y-intercept = b = 11/2

@DebbieG I think i got it now thanks!!!!
Bacon
  • Bacon
so is this right? y=(=3/5)x+9/5
AkashdeepDeb
  • AkashdeepDeb
@Bacon GO VEGAN!
DebbieG
  • DebbieG
Haha @AkashdeepDeb .... @bacon, with the exception of the fact that I think you mean that to be "-" in front of the 3, not a "=", yes, that's right! Good job!
