Final answer:
The y-intercept in the equation y = 75x + 60 represents the starting point of Karma's account balance when she first puts money in the account (x = 0).
Step-by-step explanation:
The y-intercept in the equation y = 75x + 60 represents the starting point of Karma's account balance when she first puts money in the account (x = 0). In this case, the y-intercept is 60. So, Karma's account initially had $60 in it when she made her first deposit.
