Statics: If computing the moment of inertia about the yaxis of a triangular shape in the 2nd quadrant(not touching the xaxis); would i still use hb^3 /12

encorelui2: So far, your formula looks correct. And, it is not limited to right triangles.
It does not matter whether it touches the x axis or not. And it does not matter what quadrant it is in. It only needs to have one side coincident (collinear) with the y axis, assuming b is the horizontal width of your triangle.
