The table shows the height in feet, h, of a hot air balloon and the number of minutes, t, the balloon is in the air. The equation y = 30.5t + 8.7 can be used to model the data table. Explain the meaning of the slope and y-intercept in context.

• The slope (30.5) represents the rate of change of the height of the balloon every minute, and the y-intercept (8.7) is the initial height of the balloon.

• The slope (8.7) represents the rate of change of the height of the balloon every minute, and the y-intercept (30.5) is the initial height of the balloon.
