For this case we have the following scenario:
 Carlos enrolled in a gym to play sports. Carlos pays a fee for the registration and must pay 1 dollar for each day he trains in the gym. Write an equation that models the problem.
 The equation that models the problem is:
 y = x + 1.
 The slope of the line is 1 and represents the payment of 1 dollar for each day trained.
 The intersection with the y axis is 1 and represents the payment of 1 dollar for the initial inscription.
