I think the correct answer would be the last option. The correct point slope form would be y – 8 = –2/3(x + 3). To write this, we only follow the general formula y - y1 = m(x -x1) where m is the slope which is -2/3 and x1 and y1 is the point given above. We do as follows:
y - y1 = m(x-x1)
y - 8 = -2/3 (x + 3)
