(a) Explanation Given: The graph shows the number of landline and cellphone users from 2000 to 2006 Explanation: From the above graph, we can roughly calculate the number of landline users and cellphone users using linear equations. The functions that models the landline user: L ( x ) = m x + c From the graph, estimate 2 values for the landline users. During 2000, the value is 200 million and during 2006, the value is 170 million. Substituting those value, m = ( y 2 − y 1 ) ( x 2 − x 1 ) m = ( 200 − 170 ) ( 2000 − 2006 ) m = ( 30 ) ( − 6 ) m = − 5 L ( x ) = − 5 x + c Putting ( 2000 , 200 ) in the above equation we can find c, L ( x ) = − 5 x + c 200 = ( − 5 ) × ( 2000 ) + c c = 10200 The function for landline users become: L ( x ) = − 5 x + 10200 The functions that models cellphone users: M ( x ) = m x + c From the graph, estimate 2 values for the cellphone users. During 2000, the value is 100 million and during 2006, the value is 220 million (b) To determine The point of intersection, the year when the number of cellphone and landline users will be same and find their number also. (c) To determine How well the model describes the point of intersection solved in (a).
