Question

Problem 3. Suppose that 650 pounds of coffee is sold when the price is $4 per pound, and 400 pounds is sold when the price is $8 per pound. (a) Let x represent the price per pound and y represent the pounds of coffee. List the two data points as ordered pairs (x, y). (b) Plot the data points on the grid below and connect them with a straight line. Calculate the slope (m) of this line? Pounds of Coffee (y) 800 700 600 500 400 300 200 100 0 1 2 3 4 5 6 7 8 9 10 The slope of the line is m = ___. Price per pound (x) (c) Interpret the meaning of the slope in the context of this problem. How does changing the price affect the amount of coffee sold? (d) Use the point-slope form to write a linear equation for this line. Simplify the equation to be in this form: y = mx + b. The linear equation is _. (e) Use the linear equation to predict how much coffee consumers would be willing to buy at a price of $6 per pound. The predicted amount consumers are willing to buy is ___ pounds of coffee.

The slope of the line is *m* = _____.
Price per pound (*x*)
(c) Interpret the meaning of the slope in the context of this problem. How does changing the
price affect the amount of coffee sold?
(d) Use the point-slope form to write a linear equation for this line. Simplify the equation to be
in this form: *y* = *mx* + *b*.
The linear equation is _____.
(e) Use the linear equation to predict how much coffee consumers would be willing to buy at a
price of $6 per pound.
The predicted amount consumers are willing to buy is _____ pounds of coffee.
