Solve graphically each of the following systems of linear equations. Also, find the coordinates of the points where the lines meet the axis of x in each system:

(i)



(ii)



(iii)



(iv)



i)


Unique solution at x = 2, y = 2


Lines meet x-axis at (3, 0) and (-2, 0)


ii)




Unique solution at x = 3, y = 3


Lines meet x-axis at (1, 0) and (2, 0)


iii)




Unique solution at x =1, y = 2


Lines meet x-axis at (5, 0) and (-2, 0)


iv)




Unique solution at x =1, y = 2


Lines meet x-axis at (4, 0) and (-3, 0)
