Answer: if you have a function two sets of points (Y1,X1) and (Y2,X2), then the slope that connects this two sets is A= [tex]\frac{(Y2 -Y1)}{X2 - X1}[/tex]
then Y1 = [tex]\frac{(Y2 -Y1)}{X2 - X1}[/tex]*X1 + b
and Y2 = [tex]\frac{(Y2 -Y1)}{X2 - X1}[/tex]*X2 + b
where b is a random real constant, called the y-intercept.
