1 Name: Class: Date: ID: A Multiple Choice Identify the choice that best completes the statement or answers the question.. In a linear equation, the independent variable increases at a constant rate while the dependent variable decreases at a constant rate. The slope of this line is a. zero b. negative c. positive d. undefined 2. Tara creates a budget for her weekly expenses. The graph shows how much money is in the account at different times. Find the slope of the line. Then tell what rate the slope represents. a. The slope is 50. The slope means that the amount of money in the account is decreasing b. The slope is 50. The slope means that the amount of money in the account is decreasing at a rate of $50 every 2 weeks. c. The slope is The slope means that the amount of money in the account is decreasing at a rate of $0.02 every week. d. The slope is 50. The slope means that the amount of money in the account is increasing

ANS: A m = y 2 y x 2 x = 2,000 2, = = 50 In this situation, y represents the amount of money in the account, and x represents the time. So the slope represents money. The slope of 50 means that the amount of money in the account is decreasing at a rate of time $50 every week. A B C D Feedback Correct! One unit of time on the graph represents one week. The slope is the change in y over the change in x, not the change in x over the change in y. Look at the graph to see if the slope should be positive or negative.
