The point (3, -3.65) lies on a line with a constant rate of change of -1.75. a. If the change in x is 4.2, what is the corresponding change in y? b. When x = 1.8, what is the corresponding value of y? c. Define a function, j, that expresses the value for y in terms of the value for x. 17. For the tables below, determine if the relationship is linear. If the table represents a linear relationship, write a formula to represent how the quantities change together 18. A farmer is storing water in a cylindrical holding container as shown in the figure. The farmer initially added a fixed amount of water but he mistakenly left the top off of the container, causing the water to evaporate at a constant rate. Suppose that the evaporation caused the height of the water in the container to decrease at a constant rate of 6 inches per day. If the height of the water on day 7 was 18 feet, what was the initial height of the water when the farmer first filled the container? x y 2 1.42 -1.2 -0.852 5.1 3.621 a b 0.7 1.3 -2 5.62 5.4 -2.885 r s 2.4 0.76 0.3 3.595 -1.5 6.025
