Equation of a Straight Line

		Slope
			m =	rise	=	y2 - y1
				run		x2 - x1
		Slope-Intercept Form
			y = mx + b,
			where m is the slope of the line and b is the y-axis intercept.
		General Linear Equation
			Ax + By + C = 0, when A and B are not both 0

Quadratic Equation

ax2 + bx + c = 0    x =	-b ± (b2 - 4ac)
