For this case we have that by definition, the equation of a line of the point-slope form is given by:
Where:
m: It's the slope
It is a point through which the line passes
To find the slope, we need two points through which the line passes, observing the image we have:
Thus, the equation is of the form:
We choose a point:
Finally, the equation is:

Step-by-step explanation:
Answer:
z^2 = -12y
or y = -(z^2/12)
Step-by-step explanation:
Answer:
z^2 = -12y
Step-by-step explanation:
Given the vertex at origin;
This is same as (0,0)
The focus (0,-3)
The general form is;
(z-h)^2 = 4p(y-k)
(h,k) is the vertex (0,0); so h = 0 and k = 0
The focus is given as;
(h,k + p)
so ;
k + p = -3
but k =0
so p = -3
Thus, the equation of the parabola is;
(z-0)^2 = 4(-3)(y-0)
z^2 = -12y
There's the answer hope it fits you well
