Now plot these points on the graph and join Also, three years from now, I shall be three times as old as you will be.” Is not this interesting ? Represent this situation algebraically and graphically. These two lines intersect eachother at the point (4, 2)Īftab tells his daughter, “Seven years ago, I w as seven times as old as you were then. Now we plot these points and get another line by joining them Now, we plot these points on the graphs and join them to get a line We take three points of each line and join them to get a line in each case the point of intersection will be the solution Now we shall solve these linear equations graphically as under 20 in the fair, represent this situation algebraically and graphically.Īccording to the given conditions x = 2y ⇒ x – 2y = 0 ….(i)Īnd cost of ride on wheel at the rate of Rs.
