Which is the equation of an ellipse with directrices at x = ±4 and foci at (2, 0) and (−2, 0)?

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)
