I have a loglog plot with a line that contains 5 data points. Is there a way to extrapolate the value of the slope of the line? The slope of the line is the value I need for my equation. Thanks in advanced for your help.

This is linear in log scale so you can follow Matt J's advice by using polyfit and log transforms.

Thanks Adam, I realized I posted the wrong graph, but it looks nearly the same.

You could do,
p=polyfit(log(x),log(y),1);
slope=p(1);
