The general problem is to create one formula that combines the Unit-Circle (radius = 1) equation (x^2+y^2 = 1) and the Slope Intercept equation for a line segment (y = mx+b). The problem space is inside of a unit-circle's first (45-degrees) octant (note - all x and y coordinates have positive values, within or upon the edges of the octant). Formula #1 - calculate a line segment (whose slope is '2') terminal coordinates on the circle's circumference, and its origin coordinate is x=0 (y-intercept is 0) and y is given as: 0
