Answer:
focus: (0, -5.5)
directrix: y = 5.5
Step-by-step explanation:
The equation compares to the form ...
x² = 4py
where 4p = -22 ⇒ p = -22/4 = -5.5.
The value of p is the distance from the vertex to the focus. The negative value means the focus is below the vertex at (0, -5.5).
The directrix is above the vertex by the same amount, so is y = 5.5.
2(y+1) = 3 LCD is 4
2*y + 2*1 = 3
2y + 2 = 3
2y = 3 - 2
2y = 1
y = 1 / 2
