The vertex of the parabola is at (0,0), and the focus is at (0,-7).
The focus is given by the following values:
h and k represent the x and y values of the vertex. We want to solve for p.
Set the y value for the focus equal to -7:
We know that k = 0, so we can simplify to get p by itself:
Standard form of a vertical parabola is given by the following formula:
Plug in all of your known values into the formula:
The answer is "y^2 = -28x".

The first equation is ,
First we need to solve this equation for y , and for that we need to subtract 4x from both sides, that is
Now we need to get rid of 16, and for that we have to divide both sides by 16, that is
And the second equation is
And on simplifying we will get
Which is same as the firrst equation. And in that case, there are infinite or many solutions .
