Design of Line, Circle & Ellipse Algorithms

Design of Line, Circle & Ellipse Algorithms. Slope-Intercept Formula For A Line Given a third point on the line: P = (x,y) Slope = (y - y 1 )/(x - x 1 ) = (y 2 - y 1 )/(x 2 - x 1 ) Solving For y y = [(y 2 -y 1 )/(x 2 -x 1 )]x + [-(y 2 -y 1 )/(x 2 -x 1 )]x 1 + y 1
