Reason for line not plotting?

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.

Try

 ./

Instead of

/

y = (((20*x+35000)/(70))-1)./x;

You need to learn about array and matrix operations:

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)
