Answer: 
Step-by-step explanation:
The equation of ab line that passes through two points (a,b) and (c,d) is given by :-

From the given picture , the line is passing through points (0,3) and (3,2).
Then, the equation of the line will be :-



Hence, the required equation of the line that represents the graphed function :
To find the distance between 2 numbers you must take the absolute value of the difference
|90-(-20)|
|110|
