x = 1:10:100;
y = (((20*x+35000)/(70))-1)/x;
plot(x,y)
I was wondering why the above code does not plot the function, y? As soon as the x is put in the denominator the function refuses to plot.

Use element wise operation because as you defined x as a vector you should use dot it means each element is calculated one by one.
x = 1:10:100;
y = (((20*x+35000)/(70))-1)./x;
plot(x,y)
