should rephrase 2nd point above, as ...
no solution for lambda & mu
<=> no intersection point
1 unique solution for lambda & mu
<=> 1 intersection point
infinite solution for lambda & mu
<=> the 2 lines coincide !!
no solution for lambda & mu
<=> no intersection point
1 unique solution for lambda & mu
<=> 1 intersection point
infinite solution for lambda & mu
<=> the 2 lines coincide !!
Thank you so much Mr Chau. Your explanation is very clear and I can understand it well.
