vt=-7; w=0.47; L=0.025; m=1.22; c0=34.515e-9;k=(w*m*c0/(2*L));
for vg=0:10:40
Id=k*(vg-vt).^2
plot(vg,Id,'r');
hold on;
end

You only ask it to plot one point at a time. MATLAB has no way of knowing that you want the points to be connected. If you want points to be connected in a plot then you need to give plot at least two points, the place to draw from and the place to draw to.
All of which is leading to the fact that you should not be plotting inside the loop. Instead you should be calculating the coordinates and storing them in a vector, and then you can plot the vector after the loop.
