x in (-oo:+oo)
Y+3/4 = (-1/2)*(x+5/2) // - (-1/2)*(x+5/2)
Y-((-1/2)*(x+5/2))+3/4 = 0
(1/2)*(x+5/2)+Y+3/4 = 0
1/2*(x+5/2)+Y+3/4 = 0
(1/2*4*(x+5/2))/4+(4*Y)/4+3/4 = 0
1/2*4*(x+5/2)+4*Y+3 = 0
4*Y+2*x+3+5 = 0
4*Y+2*x+8 = 0
(4*Y+2*x+8)/4 = 0
(4*Y+2*x+8)/4 = 0 // * 4
4*Y+2*x+8 = 0
4*Y+2*x+8 = 0 // - 4*Y+8
2*x = -(4*Y+8) // : 2
x = (-(4*Y+8))/2
x = (-(4*Y+8))/2
