Which of the following situations represent linear growth? Check all of the boxes that apply.

Linear growth or change happens by adding or subtracting the same amount over equal time intervals. Martin adds $25 each week, and the athlete loses 2 pounds each week, so both have a constant change. Mei-Lin earns a constant $9 per hour, so her earnings increase by the same amount for each hour worked. Cali’s 3% yearly raise is a percentage of her current pay, so the dollar increase changes over time rather than staying constant.
