Step-by-step explanation:
The given parabola has its focus at (-5,-5) and the directrix is at: y=7.
The equation of such parabola is given by the formula:
The vertex of the parabola is the midpoint of (-5,-5) and (-5,7).
The value of p is the distance from the (-5,-5) to (-5,1).
p=|1--5|=6
We substitute the values of the vertex and p into the equation to get;
