Chapter 5: Coordinate Geometry

# Generalization

Here is a general second degree equation in x and y that is used to determine the shape of the outcome graph: Ax2 + Bxy + Cy2 + Dx + Ey + F = 0.

If B = 0, then the conic section can be determined by the relationship between A and C.

Conic Section - Value of A and C

Parabola - AC = 0, A ¹ C

Circle - A = C

Ellipse - AC > 0, A ¹ C

Hyperbola - AC < 0

Coordinate geometry is so important that we have spent a great deal of time to talk about it.  You should learn this area well of firmly so that you can use it readily.  Please take a few minutes break and click here to continue to the next chapter.
