"Miss Chris" I believe you are right...I checked it with the rest of my math problem (there was more to it) and it worked!

2x+9y = - 36
First: subtract 2x from both sides (when you move a term to the opposite side, always use the opposite sign).
2x - 2x+9y = - 36-2x
9y = - 36- 2x
SEc: isolate "y" by itself - divide each term by 9.
9y/9 = - 36/9 - 2x/9
y = -36/9 - 2x/9
y = - 4 - 2x/9 or, y = -2x/9 - 4

2x + 9y = -36
```````9y = -2x - 36```{Subtract 2x from both sides}
```````` y = -2x - 36
`````````````````9````````{Divide both sides by 9}
`````````y = -2x - 36
```````````````9`````9```{Distribute 9 to both terms}
`````````y = -2x - 4
```````````````9```````````{Simplify, -36 divided by 9 is -4}
slope or m is "negetive two-ninths"
y intercept is "negetive four"

2x+9y=-36
9y=2x-36
9y=2(x-18)
y= 2(x-18)/9

2x + 9y = -36
9y = -36 - 2X
y = (-36-2x) / 9
y = -4 - (2x/9)
