Question 152911

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+8}}}
