Output

----------------------------------------------------------------------

 Linear euation creator 

 Given (x1,y1) and (x2,y2), this program computes equation of the line:

 y=mx+b 

----------------------------------------------------------------------
Please enter x1 y1:  -1 -1 

Please enter x2 y2:  -1 -1 


----------------------------------------------------------------------
Slope: 3.0

y-Intercept: 2.0

Equation of the line: y= 3.0x + 2.0


----------------------------------------------------------------------
Please enter a value for x:  0.0
