Answer:
(0, -3)
Step-by-step explanation:
The vertex is halfway between the directrix and the focus. The vertex is at (0, 0) and the directrix is a (0, 3). There are 3 units between them, so that means that the focus is 3 units the other way at (0, -3).
The given function is

And it is given that 
On using this information, we will get

And the other point is 
Using this point, we will get

Dividing both equations, we will get

Taking ln to both sides


Performing back substitution ,

Answer:
A system of two equations can be classified as follows: If the slopes are the same but the y-intercepts are different, the system has no solution. If the slopes are different, the system has one solution. If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
