Point-Slope Equation Form might be best choice. Not absolutely necessary.

m=%283-1%29%2F%28-3-0%29=-2%2F3, the same slope you want for your parallel line.

Generally, formula for slope: m=%28y-v%29%2F%28x-u%29
y-v=m%28x-u%29
YOUR specific point that your line contains is (0,9)---------- On another thought, *Slope-Intercept form would be best choice!
highlight%28y=-%282%2F3%29x%2B9%29


* Reason I changed the choice of equation form is because the point to be on the sought line is its y-intercept.
-
y=mx%2Bb
m is the slope.
b is the y intercept also expressible as (0,b).
