Question 240467
there are two foci, in a VERTICAL line, symmetric about the x-axis


if this were a hyperbola, there would be NO x-intercepts


so you have an ellipse
___ centered at (3,0)
___ the length of the minor axis is ___ 2b = 7 - -1 = 8 ___ so, b = 4
___ distance from center to focus (c) is 2
___ a^2 = b^2 + c^2 = 16 + 4 = 20


[(x - 3)^2 / 16] + [(y - 0)^2 / 20] = 1
