Given:
The values of a linear function are and
.
To find:
The linear function.
Solution:
If a linear function passes through two points, then the equation of the linear function is:
The values of a linear function are and
. It means the function passes through the points (-9,8) and (0,1). So, the equation of the linear function is:
Adding 8 on both sides, we get
Putting , we get
Therefore, the required linear function is .
