for mcap=0:0.1:100
    mbat = (35000-10000*mcap)/3000;
end
for mbat=0:0.1:100
    mcap = (35000-3000*mbat)/10000
end
plot(mbat,mcap,'ro')

Please can someone make a correction for me? i want to plot this graph so that all the intersection points should appear, but I am having only the last series intersection point appearing on the graph.

Thanks you

You didn't allocate for each element of the output arrays but computed each point one-at-a-time by using an unneeded for...end loop. Use MATLAB array syntax instead--

v=0:0.1:100;
mbat = (35000-10000*v)/3000;
mcap = (35000-3000*v)/10000;
plot(mbat,mcap,'ro')

NB: I also took out the reuse of same variable and redefinition of mcap as both input and output in lieu of a single variable, v, for the independent variable.
