Score on last attempt: Score in gradebook: 10 out of 2. 0 out of 2 The following table shows two ordered pairs for a linear relationship. (Try drawing a graph and place these points on the graph. Use your drawing to help you reason about the given information.) Submit F a. Using the information in the table, determine the constant rate of change of y with respect to a. (Be careful keeping track of any negative signs.) Ay Az b. Write the formula that represents the value of y with respect to Preview 0 12.5 Preview V -13 62
The given graph shows a linear relationship (meaning there is a constant rate of change of y with respect to z). Ay Az 4 3 (5, 1) Submit a Use the purple "X" to explore how z and y change together in this relationship. b. Determine the value of the constant ratio of (Ay) to (Ar). [You will need to use two ordered pairs to first determine a correpsonding pair of change values, Ay and Ar.] for all corresponding changes. 6.55, 1.46) Drag the purple X on the z-axis to vary the value of z. Notice that the point (5, 1) is on the graph $ 9 Preview *Try again. Make sure you determine two points and then calculate (1) the change in y from the first ordered pair to the second, (2) the change in z from the first ordered pair to the second, and (3) the ratio of those changes (being careful with the order of division) c. Drag the purple "X" again and look at the corresponding sizes of the red and blue vectors. When you compare their lengths, you should be able to justify why the value in part (b) makes sense.
