The Algebra of Straight Lines
Posted April 2, 2012
by Lensyl Urbano
A quick graphical calculator for straight lines  based on This. It's still incomplete, but it's functional, and a useful complement to the equation of a straight line animation and the parabola graphing.You can graph lines based on the equation of a line (in either the slopeintercept or pointslope forms), or from two points.
Straight Lines
SlopeIntercept Form  Two Points  PointSlope Form 

y = m x + b 
(x_{1}, y_{1}) = ( , ) 
y  y_{1} = m ( x  x_{1}) 
y =
x +

(x_{2}, y_{2}) = ( , ) 
y 
=
( x 
)

x intercept:  Slope:  Equation: 
y intercept:  Points:
