I am very new to Matlab and was wondering how to graph the function y= (x-1)/(x+1)

I have written the code: x= -5:5; y= (x - 1)/(x + 1); plot(x,y)

It does not come up with any errors but when I select Run my graph does not show

 Just include a . before division  

x= -5:5
y= (x - 1)./(x + 1)
plot(x,y)
