Struggling with line()

Hi,

I am trying to plot a line using the line command:

code is the following

a = [0 0]; b = [40 0];

line(a,b, 'color', 'k','LineWidth',2)

However, when I plot I get a line from (0,0) to (0,40) like so:

I have absolutely no idea why this is happening and have tried running on a friend's computer to make sure I am not going crazy. Please let me know if there is a glaring issue here that I have missed or how I can fix this. Thanks in advance

The first parameter is a list of x coordinates. The second parameter is a list of y coordinates.

The parameters are not source xy pair and destination xy pair.
