The table shows the calories burned during exercise. A 2-column table with 5 rows. The first column is labeled minutes of exercise with entries 15, 30, 45, 60, 75. The second column is labeled calories burned with entries 75, 150, 225, 300, 375. Which statement is true? The y-intercept of the function is (15, 75). The rate of change is 15 calories burned per minute. A linear function to model the calories burned, y, as a function of time in minutes, x, is y = 5x. An exponential function to model the calories burned, y, as a function of time in minutes, x, is y = 5x.
