Answer: y = (1/3)x-2
Step-by-step explanation:
You can rearrage the equation to:
[tex]3y=x-9[/tex]
Then solve for y:
[tex]y=\frac{1}{3} x-3[/tex]
We now have our slope of 1/3. We can plug in our point and slope to the equation y=mx+b to get the y-intercept:
[tex]-1=\frac{1}{3}(3)+b[/tex]
[tex]-1=1+b[/tex]
[tex]b=-2[/tex]
Now we have our slope and y-intercept we can form the equation:
[tex]y=\frac{1}{3}x-2[/tex]
