Answer:
If it's parallel it has to have the same slope
y=-3x-3
The second number is the y intercept. If you enter the x value 1 in the equation and get -6 then the y intercept is correct lets say you have
y=-3x
if you enter 1 you get y = -3
what plus -3 is -6? -3. the y intercept is -3.
Hope its correct and it helps
