Answer:
I won't be able to give you a numerical answer but that's not what your question's asking anyway. Just put a dot at the coordinates (0,-3) and one at (-2,3) and connect them. That's your first line. For the second question put a dot at the intersections (0,1) and one at (-4,-3) and connect them. You should be able to find a point where the two lines intersect. That's the point you need. If you still can't find it, then continue the lines or message me at riztofu on insta. I'll solve your question then.
