You mean you want to plot 2 lines on the same graph? Any basic Matlab toturial should teach you this. Have you done one?

In order to place mutliple plot on same figure we can use hold on functionality
As a example
x = linspace(-pi,pi);
y1 = sin(x);
y2 = cos(x);
plot(x,y1); % first line
hold on
plot(x,y2); % second line
hold off
