Quintin is participating in a walkathon. He writes the equation m = 8d + 6 to represent the amount of money he collects from each sponsor for walking d kilometers. What number represents the rate of change? What number represents the initial value? Explain.

8 represents the rate of change while 6 represents the initial value

Step-by-step explanation:

For every additional kilometer d that we walks, d increases by 1 and m increases by 8 times d. So 8 represents the rate of change.

At d = 0, meaning d = 0, m = 8*0 + 6 = 6. So he gets 6 at before having to walk. So 6 represents the initial value
