For Exercises 6 and 7, refer to the Amusement Park investigation on page 627. Jakes sawdust spreader is on its way from the Sledge Hammer to the Roller Coaster. When he has gone 0.6 mi, it breaks down. See the graph in the investigation on page 627. Each unit on the graph is 0.1 mi, so 0.6 mi is equal to 6 units. a. Find the equation of the line connecting the Roller Coaster and the Sledge Hammer. b. Write the distance formula using (x, y) as the breakdown point and the location of the Sledge Hammer as the second point. c. Replace y in your distance formula with the expression equal to y that you found in 7a. d. Set the distance equal to 6 units (0.6 mi) and use a calculator graph to solve for x. e. Give the coordinates of the breakdown point.
