Since the candle starts at 8 inches, this means that the constant is b=8. Also, because the candle burns at a rate of 1.5 inches per hour, this means that the slope is m=-1.5 (note: the rate is negative since the length of the candle is decreasing). So the equation that models the candle is


y=-1.5x%2B8
