Answer:
y=-3x+9
Step-by-step explanation:
The lines are parallel, so they must have the same slope, and a different y-intercept. They must have the same slope so they never intersect, and a different y-intercept so that one is not directly on top of the other.
[tex]y-y_{1} =m(x-x_{1} )\\y-3=-3(x-2)\\y-3=-3x+6\\y=-3x+9[/tex]
