Solve the problem.
The graph models the average amount spent annually on entertainment per household in Country X from 1981 to 1987. (i) Find the slope of the line. (ii) Find a point-slope form for the line. (Answers may vary.)
A. Slope is 675; point-slope form is y = 675(x - 1982) + 1500.
B. Slope is 825; point-slope form is y = 825(x - 1984) + 2850.
C. Slope is 375; point-slope form is y = 375(x - 1982) + 1500.
D. Slope is 525; point-slope form is y = 525(x - 1984) + 2850.
