candle burned at a rate of 1.5 inches per hour and its initial length was 15 inches.
Required:
To write the equation.
Step-by-step explanation:
Now make a table
Number of hours Length of the candle remaining
0 15
1 13.5
2 12
3 10.5
Here the general foem of equation is

Where m is the slope

Now the equation is

Now we have to find the value of b, by consider (0,15)

Now the equation is

Final Answer:
