If you tried to check, the point (-3,-1) passes through the line y=x+2 meaning the vertex is exactly in the point (-3,-1)

The length of the latus rectum is 6 units meaning    4p=6

Since you said that the parabola is parallel to the y-axis, the equation will look something like this: (x-h)^2=4p(y-k)

so if you try to input all the given you'll get this:

(x+3)^2=6(y+1)

although i'm not so sure since it wasn't mentioned if its facing upward or downward
