Linear Function 1 has the lesser initial value, with an initial value equal to $0 while Linear Function 2 has an initial value equal to $40.

Answer 1

Linear Function 1 has the lesser initial value. Lionel's plan is y = 45x so the initial value (at x=0) is $0, while Linear Function 2 has initial value $60 (y = 40x + 60).
