Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
5x-8y=40
===>8y-5x=-40
8y-5x=-40
Both the lines coincide.

All the points on the line are the solutions to both the equations. So, the system of equations has infinite number of solutions.
So, the system of equations is consistent and the equations are dependent.
