Answer:
no it is not
Step-by-step explanation:
3x+9y=1 simplified is
9y=-3x+1
y=-1/3x+1/9
this is the exact same equation as 3x+9y=1, so you cannot find another line thats parallel to it and passes through that same point (it'll always be that point)
x²/4 + y²/16 = 1
Foci on the y axis: major axis parallel to y axis
x²/b² + y²/a² = 1
429.9
yes
