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. x² + Cy2 +Dx+Ey + F = 0
Given 4 points on a vertical ellipse (-1.366, 0), (0, 2.241), (1, -12), and
(4, 2.43). Select the missing coefficients (answers have been rounded
to the nearest tenth).
