Best ResponseYou've already chosen the best response.0Brian and Cyril spend a certain amount of money from their money box each month to buy plants. The table shows the relationship between the amount of money (y) remaining in Brian's money box and the number of months (x): Function 1: Number of Months (x) Amount Remaining (dollars) (y) 1 65 2 59 3 53 4 47 The equation shows the relationship between the amount of money, y, remaining in Cyril's money box and the number of months, x. Function 2: y = –8x + 65 Which statement explains which function shows a greater rate of change? Function 2 shows a greater rate of change, because Cyril spends $8 each month and Brian spends $6 each month. Function 2 shows a greater rate of change, because Cyril spends $65 each month and Brian spends $18 each month. Function 1 shows a greater rate of change, because Brian spends $18 each month and Cyril spends $57 each month. Function 1 shows a greater rate of change, because Brian spends $6 each month and Cyril spends –$8 each month.

Best ResponseYou've already chosen the best response.0use the slope formula to find the rate of change for function 1 \[m=\frac{ y_2y_1 }{ x_2x_1}\] Pick any two points to plug in

Best ResponseYou've already chosen the best response.0you can use 1 for x_1 and 65 for y_1. Now pick another point for x_2 and y_2.

Best ResponseYou've already chosen the best response.0Each pair of numbers in that table represent a point on a line. They're asking you to find the slope of the line that has the points (1, 65), (2, 59), (3, 53), and (4, 47). Does that make sense?

Best ResponseYou've already chosen the best response.0not really. the direction matters. ROC of 8 means the function is increasing. ROC of 8 means it's decreasing

Best ResponseYou've already chosen the best response.0btw these are the answer choices: A: Function 2 shows a greater rate of change, because Cyril spends $8 each month and Brian spends $6 each month. B: Function 2 shows a greater rate of change, because Cyril spends $65 each month and Brian spends $18 each month. C: Function 1 shows a greater rate of change, because Brian spends $18 each month and Cyril spends $57 each month. D: Function 1 shows a greater rate of change, because Brian spends $6 each month and Cyril spends –$8 each month.

Best ResponseYou've already chosen the best response.0For function 1 let's just consider the 2 points (1, 65) and (2, 59). This is how you put them into the slope equation dw:1435794971386:dw

Best ResponseYou've already chosen the best response.0i no the slope equation is y=mx+b

Best ResponseYou've already chosen the best response.0by slope equation, I meant the equation you use to find the slope of a line. y = mx + b is the slopeintercept form of a linear function. It uses the slope, but sometimes, like in function 1, you don't have an equation in that format. So you have to find the slope using points and the equation above.
