2. Use the following data to construct a diagram that has corn along the vertical and F-15s along the horizontal axis

Corn (in millions of bushels)	F-15s (in thousands)
18	0
17	1
15	2
12	3
7	4
0	5

Assume that the first pair of values corresponds to point (a), the second pair to point (b), the third pair to point (c), the fourth to point (d), and the fifth to point (e). Calculate the values of the slope of the segments (ab, bc, cd, de, ef) and reflect on their significance.
