@johnnyy999 you're wrong cause we have two variables. We couldn't possibly find the solution.

actually it's a two variable solution

so it's possible

Subtract 8x from both sides –9y = 11 - 8x Divide both sides by -9 \[y = -\frac{ 11 }{ 9 } - 8x\]
Constanceleak
  • Constanceleak
i thought 8x needed to be divided by 9
OnePieceFTW
  • OnePieceFTW
right that's correct \[y = \frac{ -11-8x }{ -9 }\]
OnePieceFTW
  • OnePieceFTW
Sorry :/
Constanceleak
  • Constanceleak
It's ok
Constanceleak
  • Constanceleak
\[y=-9/8x-9/11\]
Constanceleak
  • Constanceleak
y=9/8x+11/8
Constanceleak
  • Constanceleak
y=-8x-11
Constanceleak
  • Constanceleak
or y=8/9x-11/9
Constanceleak

those are the only answers

It's the last one :) I believe y=8/9x -11/9

Hope that works for you.

But we don't have a 9x ever in the equation. Are you sure one of the choices isn't \[y=\frac{ -8x }{ -9 } + \frac{ 11 }{ -9 }\]
OnePieceFTW

11/-9
