Coordinate geometry is a very important area of math. It combines algebra with geometry. It is based on idea that algebra equations can be represented as geometric shapes. This blog also has algebra and geometry as two separate categories.

There is an amazing regularity between degree of equations and the geometric shapes they form. All linear equations in two variables give straight lines. Lines formed by linear equations differ only in their positioning in a coordinate plane. This article includes example problems involving only simple linear equations.
