The red curve is a piecewise linear interpolation, not really a curve, just connect the dots by the plotting routine.

The green lines are just vertical lines, so a fixed value of x. So all you are asking is how to use linear interpolation. You can find both solutions at once. interp1 will do it for you.

yred = interp1(xmin,ymin,[552.5, 723.5],'linear')
yred =
       75.654       78.324
