From 1990 to 1999, the amount spent to purchase a car exported to a certain country increased at a rate of $1,780 each successive year. In 1995, the average amount spent to purchase a car exported to that country was $25,400. Let x represent the number of years since 1990, and let y represent the amount spent to purchase a car exported to that country (in thousands of dollars). Identify the marginal change b and the given ordered pair (x, V). b = (x1,y1) Write an equation in point-slope form using the given ordered pair (x, y) for the amount spent to purchase a car exported to that country from 1990 to 1999. Sketch a graph of the equation for x = 0 to x = 9. y 35 30 25 20 15 10 5 35 30 25 20 15 10 5 1 2 3 4 5 6 7 8 9 x 1 2 3 4 5 6 7 8 9 35 30 25 20 15 10 5 35 30 25 20 15 10 5 1 2 3 4 5 6 7 8 x 9 x 1 2 3 4 5 6 7 8 9
