Answer 1

You can use desmos to graph

Answer 2

first the equation needs to be put into slope-intercept form: so subtract x from both sides first:
x-x + 3y = -x-9
3y=-x-9
Now we divide both sides by 3:
y= -1/3x-3
Note: the number without the variable (in this case -3 is always the y-intercept)

Answer 3

Thank you both this helped out a lot! :3
