Maddy and Caitlin spend a certain amount of money from their money box each month to buy bracelet-making supplies. The table shows the relationship between the amount of money (y) remaining in Maddy's money box and the number of months (x): Function 1 Number of Months (x) Amount Remaining (in dollars) (y) 1 100 2 80 3 60 4 40 The equation shows the relationship between the amount of money (y) remaining in Caitlin's money box and the number of months (x): Function 2: y = −18x + 120 Which statement explains which function shows a greater rate of change? Function 2 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends $18 each month. Function 2 shows a greater rate of change, because Maddy spends $100 each month and Caitlin spends $120 each month. Function 1 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends −$18 each month. Function 1 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends $18 each month.

function2, what is the slope?
i got m=−18,b=120 where m is the slope and b is the y-intercept
-18 is a slope of function 2 Now, function1, what is its slope?
yes, so the slope is -20, right?
Now compare the two, -18, and -20, which one is steeper?
so function 1 has the slope steeper than function2, that is the rate of change of function1 is greater than ...... which one is the correct answer?
A or D?
A i was just smilling
again, which one do you choose??
A i pick A
OMG!! you didn't pay attention to my guide!!! waste my time. it's D
i thought u didnt understand what i was saying GOSH
