Solving Simultaneous Linear Equations Graphically

Use the slider to change the values of m1, c1, m2 and c2 to form two linear equations.[br]Solve the two linear equations either by Substitution or Elimination Method.[br]Observe the coordinates of the intersection point.
Is it true that the solution of the two linear equations is always the x and y coordinates of the intersection point?
