What does the sign of the three coordinates tell you about where in the plane the point is? (You might want to reflect on the fact that the lines forming the sides of the triangle, when extended, divide the plane into seven regions.)"

So yeah, for the first question I think it means that it is the origin (0,0). Is that right?

As for the second one, at first I thought it had something to do with the 4 quadrants, that if it is positive it is in the first quadrant, and if it is negative it has to be in the third quadrant...but I don't think that is the right answer because of the extra information given between brackets. :S
