BMI graph, 3 variables on 2D graph

How can i create a graph in GUI (it's BMI graph), where x is from 0 to 2.5, y is from 0 to 650 and i want to draw a few lines let's call them "c" (y/x^2=c) and i would like to draw lines for c=16.5,18,25,30,35 and 40. How can i do that to display 3 variables on 2D graph and i only want to count c, x and y should just change by 0.1 and 1.

If you want to use 3 variables on 2D plot, then you can use contour or contourf or surf or surfc.
clc
clear
lat=(1:10)';
lon=(1:20)';
rf=randi(20,10,20);
figure()
contourf(lon,lat,rf,'linecolor','none');
figure()
[x,y]=meshgrid(lon,lat);
a=surf(x,y,rf,'FaceAlpha',0.5,'EdgeColor', 'none')
figure()
surfc(x,y,rf,'FaceAlpha',0.5,'EdgeColor', 'none')
