tuition and fees 16,077 18,068 20,042 22,306 24,814 26,766 28,987 30,097
(a) sketch a graph of the data. let c correspond to tuition and fees and let t correspond to year.
a.
b.
c.
d.
do the data appear to lie roughly along a straight line?
a. no, they appear to lie on a curved line.
b. no, they appear to lie in a v - shape.
c. no, they seem to be scattered randomly.

Explanation:

Step1: Analyze data trend

The tuition cost C increases as year t increases (from 2000 to 2013: 16077→30097).

Step2: Match with graph options

• Option A: Points rise consistently with t, matching the increasing trend.
• Option B: Points fluctuate, not matching.
• Option C: Points are flat, not matching.
• Option D: Points fall, not matching.

Step3: Check linearity

The increasing points in Option A form a roughly straight upward line.

Answer:

A. (graph with consistently rising points), A. No, they appear to lie on a curved line.
