How would I go about plotting an equation?

I need to plot the following equation: (y/34) + (x/84) = 1; with 'y' and 'x' being numbers from 0-100. I know how to define x and y(i.e. x = (0:100) and likewise with 'y'), but when I try plotting the equation I just get a blank graph, can anyone guide me in the right direction, please?

You are incorrect in your assumption that you define 'y' in the same manner as 'x'. To 'plot the equation' you first have to rearrange for y in terms of x, then plug your vector for x into that, and finally plot.
x = 0:100;
y = % you work it out
plot(x,y);
