I want to find the distance between the graph and straight line as shown below,
Thank you.

Do you have the specific points on the curve and the line available?

It looks like you need to rotate the whole picture (red line + blue curve) to minus the slope of the red line.
After rotation the redline become horizontal; then tthe distance is just the differential y-coordinate (after rotation) of the any blue points to the y-coordinate of the horizontal red line
Rotation is multiply x-y coordinates by matrix, see wiki
R := [cos(theta) -sin(theta);
sin(theta) cos(theta)]
R*[x;y]
Use theta as minus the slope of red line. You must know the redlinne equaltion, so its slope somehow.
