Pink part: Y=54+0X (For the right part:) Blue line: Y=18+3X Green line: Y=227-8X Pink and blue lines intersect at (12,54) -- that's X:12, Y:54 Blue and green lines intersect at (19, 75) -- that's X:19, Y:75 Green and brown lines intersect at (25, 27)
You may want to use different values for your lines; but you will have to compute the coordinates for new intersections. For example: if you use pink line Y=60+0X Pink and blue lines will intersect at (14, 60) -- that's X:14, Y:60
