if you have two lines, one being at 45 degrees and the other one perpendicular to the first, and you have the y positions of where each line intersects the y axis, then using only the y coordinates of the lines and the point of intersection, could you define any point on a 2-d plane? the values can be negative. I’m sorry if i worded this confusingly. if you have a question, please reply.
I think you are describing a right triangle with the hypotenuse parallel to the x axis, is that right?

No, because if the intersections are (0,10) and (0,-10) then the point could be (10,0) or (-10,0).

If we add to the coordinate convention that the line with the first coordinate is the one with the positive slope(or the other way around, whatever), then ( (0, 10), (0, -10) ) could only be (-10, 0), so that might solve the ambiguity problem.
Although, that’s adding something new to the OP’s proposal that might diverge from the original intent.

thank you, that is what I did actually originally meant. You just worded it better.
