Answer 1

(a) -0.4

(b) negative, decreased

(c) -0.4, 0.4%

Explanation:

(a)

The slope can be calculated as follows:

`m=(y_2-y_1)/(x_2-x_1)`

We substitute the given points in the graph and obtain the slope, like this:

`m=(7.3-11.8)/(2012-2000)=(-4.5)/(12)=-0.375\cong-0.4`

(b)

The slope is negative, which means that as time progresses the percentage decreases.

(c)

Since the slope of the line is -0.4, the change in the percentage of freshmen per year who planned to major in business is 0.4%, since each year it decreases by 0.4%
