Hussain -The center (h,k) of the ellipse is at the midpoint between the two foci. (h,k) = (-4 , -3)The distance from the center to either foci is c.c = √(a^2 - b^2)b is half the length of the minor axis, so b = 4Now plug in c and b into the formula above and solve for a.That is all you need to write out the equation for an ellipse: a, b, h, and k.Hope that helps
