Line: 2-Point Equation

This example uses the point-slope form for the equation of a line when 2 points are known. It extendx/contains the line within the X-axis and Y-axis
Scenerio:
Point-slope:
m=(y2-Y)/(x2-X)
y – X = m*(x – Y)
equation:
y=m*x-m*X+Y
x=(y+m*X-Y)/m

Green line is original points. Dashed line ends at x,y axis (black dots).
My Line
Known Points
x1= y1= x2= y2=

X,Y Axis Points (black dots)
x1= y1= x2= y2=
