//y= 0.4x+0.5 for x=(0, 2.375)
//y= -0.4x+2.4 for x=(2.375, 4.75)
//It should go from 0.5 for x=0 to 1.45 for x=2,375 and then back to 0.5 for x+4.75. 
//Idealistically this function should be periodic and go from x=0 to x=2000 (a zigzag shape),
// however since I can't even get one "triangle" I haven't tried to do anything more advanced.
