2,125,764 because every year it is multiplier by three which reaches to 2,125,764
The answer to the questions
3.) y-intercept = 2. The graph will be a straight line passing through points (0, 2) and (2/3, 0)
4.) y-intercept = -1. The graph will be a straight line passing through points (0, -1) and (2, 0)
5.) y-intercept = 2. The graph will be a straight line passing through points (0, 2) and (3, 0)
