x in (-oo:+oo)
y+6 = 2*(2/3)*(x-7) // - 2*(2/3)*(x-7)
y-(2*(2/3)*(x-7))+6 = 0
(-4/3)*(x-7)+y+6 = 0
y-4/3*(x-7)+6 = 0
y-4/3*(x-7)+6 = 0
y-4/3*x+6+28/3 = 0
y-4/3*x+46/3 = 0
y-4/3*x+46/3 = 0
y-4/3*x+46/3 = 0 // - y+46/3
-4/3*x = -(y+46/3) // : -4/3
x = (-(y+46/3))/(-4/3)
x = 3/4*(y+46/3)
x = 3/4*(y+46/3)
