Question

You're looking at a line graph. It shows the average price of a concert ticket

since 2000. Here are some of the points on the line: (2000, $40), (2001, $47),
(2002, $51). Based on this trend, which of the following would you expect to
see on this line graph?
LES
HE
O A. (2003, $35)
O B. (2005, $75)
O C. (2006, $500)
O D. (2004, $35)

Answer 1

With the few points given, we cannot identify the exact relationship between the year and the corresponding ticket price. In other words, we can not identify the slope. We do know that we are looking at a line graph and that there is a positive association between the two variables. With knowledge of this, B is the only sensible option.

answer: B
