Previous Question: Southern Phone Company is promoting a new cell phone service plan: a customer can make up to 500 minutes of calls each month for $39.99. If the number of minutes used in a month exceeds 500, then the function c = 0.40(m - 500) + 39.99 describes the monthly charge, c, in dollars in terms of m, the total number of minutes used. Which of the following statements best describes this function? Next Question: Which of the following is not a correct description of the graph of the function y - 2x - 7? a) The graph of the function contains the point (-2, -3), and when the value of x increases by 1 unit, the value of y decreases by 2 units. b) The graph of the function contains the points (-1, -5), (2, -11), and (4, -15). c) The graph of the function is a line that passes through the point (0, -7) with a slope of -2. d) The graph of the function contains the points (0, -7), (1, -9), and (3, -1).
