ok, so the tilt is thhe slope
slope=rise/run
if the slope is negative, then it is tilted right downwards
horizontal is 0/infinity slope or 0 slope, it is normally in y=something form
vertical slope is undefined slope, it is normally in x=something form
so
in form
ax+by=c
slope=-a/b
so
6x-2y=8
slope=-6/-2=3
3 is positive, so tilted right upward
