## need help for graph and program...

hey friends I have solved linear equation numerically and in the end i have ploted pointplot graph where every point in graph is taken maunally. Please help me how to write code that at specific values of x required points from

Solution := backsub(S)

should automatically be ploted where x=i*h and h=1/32 where i varies from 0 to m.
