No worries its confusing for sure... Esp the "Matrix" class... Luckily we have a few cool shortcut functions that make it easier for us... In this case you want to use translate. The Matrix class basically allows us to transform the bitmap before pasting it where we want it... Try this then make the changes as necessary to suit your needs.
var _mtx:Matrix = new Matrix()
graphics.beginBitmapFill(bitmap, _mtx, false, false);
graphics.drawRect(100, 100, test_image.width, test_image.height);
