PROOF OF MY CENTRAL POINT THEORY



FUNDAMENTAL PROOF OF THE CENTRAL POINT AND ITS SLOPE

At central point (xg, yg) in the ordered pair (X, Y) of straight line equation Ax+By=C, the formula for xg and yg  are given as;

Xg = C/2A

Yg = C/2B



PROOF!

Given Ax+By=C, the central pair can proved by equally pairing x to y.

i.e   Ax = C-By………(1)
       
       By = C-Ax……(2)

Equating Ax in equation(1) to C-Ax in equation (2), we have

Xg = C/2A

Also, equating By in equation(2) to C-By in equation (1), we have

yg = C/2B




THE SLOPE

At central point, the slope of straight line equation Ax+By=C is given as m = -yg/xg where xg and yg denoted as central point pairs and m denoted as slope.



 PROOF!

 Given Ax+By=C, the slope of the straight line can be determined by moving term Ax to right hand side and divide both side by the constant B

Y = -(A/B)x + C/B

But let m=-A/B(slope) and b=C/B(intercept), hence we have

Y = mx+b……..(1)

Equally pairing m to y, we have

Y = mx+b…….(2)
-mx = b-y……(3)

Equating y in eqn(2) to b-y in eqn(3), we have

Y = b………(4)
Also, equating –mx in eqn(3) to mx+b in eqn(2), we have

M =-b/2x……..(5)

Putting eqn(4) into eqn(6), we have

M= -y/x  or  m= -yg/xg:  hence proved!
