Check the picture below.
now, keep in mind that the focus point is at 3,0 and the directrix is to the left-hand-side of it, therefore, is a horizontal parabola, and it opens to the right-hand-side, like in the picture.
keep in mind that the vertex is half-way between the focus point and directrix, at a distance "p" from either one, notice the "p" distance is just 3 units, since the parabola is opening to the right, "p" is positive.

3x - 2y + 2 = 0 → -2y + 2 = -3x → -2y = -3x - 2 → y = x + 1
x - y + 3 = 0 → -y + 3 = -
x → -y = -
x - 3 → y =
x + 3
These two equations have the same slope but different y-intercepts so they are parallel lines. (aka inconsistent).
Answer: Inconsistent, (0, 1), (0, 3)
