The linear equation that defines the height of the candle as a function of time is:
h(x) = H - (1.8 in)*x
Here we only know that the candle burns at a constant rate of 1.8 inches per hour. But there is missing information, as we don't know the initial height of the candle.
So, let's define H as that, the initial height.
Initially, the height will be H, and for each hour that passes, the height decreases by 1.8 inches. So after x hours, the height is:
h(x) = H - (1.8 in)*x
This linear equation defines the height of the candle as a function of time.
