Answer:
The equation of the line using function notation is

Step-by-step explanation:
Given points are (-20,5) and (-36, 9)
Now to find the equation of the line passes through these points
Let
and
be the two given points (-20,5) and (-36, 9) respectively.
To find slope





Therefore 
The equation of the line is of thr form y=mx+c
The point (-20,5) passes through the above line and 




Therefore 
Therefore the equation of the line using function notation is
