1) Not a function 2) function 3) function
Step-by-step explanation:
Use the vertical line test. If you draw a line on every vertical line on the graph and you see two points, it is not a function.
Answer:
(-4,-5)
Step-by-step explanation:
The slope of the line passing through (3,5) and (-2,1) would be:
It would be:
y2 - y1 / 2 and x2 - x1 / 2
= 1 -5 / 2 and -2 -3 /2
= -4/2 and -5/2
= (-4,-5)

Finding the line of best fit is something a Machine Learning Model would do.
This particular ML model is called "Linear Regressor" or "Linear Regression Model". Look it up and there are definitely calculators for it, as it is relatively simple.
You can also, if you know how to use ML libraries and code, use Python to determine the value of .
