An ellipse or hyperbola uses the general form
Ax² + Cy² +Dx + Ey+ F = 0. Solving for 5 unknowns. (A, B, C, D, E, F)
requires 5 equations, needs 5 points given. But if one of the coefficients is
divided out (A or C), then only 4 coefficients remain and only 4 points are
needed. 2²+ Cy² +Dx+ Ey+ F = 0
Given 4 points on a vertical ellipse (3.75, 0), (0, 2.71), (1, -7), and (-1, -5.725).
Select the missing coefficients (answers have been rounded to the nearest
tenth).
