For this case we must find the graphical solution of the following system of equations:
In the attached image it is observed that the lines are parallel, they are intercepted in all the points. In addition, it is observed that if we divide the second equation by 5 we obtain:, if we now multiply by 3 we obtain:
. Being shown that the lines are equal, therefore, the system has more than one solution.

Answer:
Step-by-step explanation:
we know that
The standard equation of a horizontal parabola is equal to
where
(h,k) is the vertex
(h+p,k) is the focus
In this problem we have
(h,k)=(0,0) ----> vertex at origin
(h+p,k)=(-4,0)
so
h+p=-4
p=-4
substitute the values
