You can put this solution on YOUR website!
Let y = the area and let x = the width, and let k = length, and we are reminded that k does not vary.
Area is kx.
y=kx

You need an actual value for length, k, to graph anything. You would alternatively need two data points (x,y) allowing you to determine k, the length.
