For a year, Charlie records the balance of his checking account at the end of each month. His data can be represented by the linear model y = 213.73x + 75.62 , where x is the number of months and is the account balance. Fill in the blanks with the values that correctly complete the statement. Based on the linear model, Charlie began with $​​ (a)   in his checking account, and the balance of his checking account increases by ​ (b)   each month.​ ​
