x in (-oo:+oo)
y-(5/4) = -((5/8)*(x-4)) // + (5/8)*(x-4)
(5/8)*(x-4)+y-(5/4) = 0
(5/8)*(x-4)+y-5/4 = 0
5/8*(x-4)+y-5/4 = 0
(5/8*4*(x-4))/4+(4*y)/4-5/4 = 0
5/8*4*(x-4)+4*y-5 = 0
5/2*x+4*y-10-5 = 0
5/2*x+4*y-15 = 0
(5/2*x+4*y-15)/4 = 0
(5/2*x+4*y-15)/4 = 0 // * 4
5/2*x+4*y-15 = 0
5/2*x+4*y-15 = 0 // - 4*y-15
5/2*x = -(4*y-15) // : 5/2
x = (-(4*y-15))/5/2
x = 2/5*(15-(4*y))
x = 2/5*(15-(4*y))
