The equation of straight line will be calculated for following points:

Number of points n: 2

x
y

Due to check if data has been input correctly, please check if sum of all x and y is the same as displayed, especially decimal places:

Control sum of all x = 0
Control sum of all y = 0

Then some parameters listed in table below should be calculated :

x
y
xy	0	0
	0	0
	0	0

Then, to find out coefficients of the straight line we need:

	=	0
	=	0
	=	0
	=	0
	=	0
	=	0
	=	0
