25-89.95=64.95
The rate of change from 1995 to 2010 is 20 students per year and the linear function that models the data will be:
<em><u>Explanation</u></em>
In the year 1995, there were 1200 students and in the year 2010, there were 1500 students.
If represents the year and represents the number of students, then two points in form of will be: and
So, the rate of change or slope = (change in value of y / change in value of x)
Now, plugging slope = 20 and first point into <u>point slope form of linear equation</u> , we will get.....
7920
12C3 × 9C2
= 220×36
= 7920
