Use the slider to change the values of m1, c1, m2 and c2 to form two linear equations. Solve the two linear equations either by Substitution or Elimination Method. 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?
