Answer:
It is slope of a line which is 4
Explanation:
We are given that the given points are generated by a linear function. A linear function is ta straight line that can be represented by:

Here m is the slope
The slope of a line is given by the formula:

In order to find the slope from the table we take any two pairs of inputs and outputs i.e. x and y
So here we take
(x1,y1) = (-6,-16)
(x2,y2) = (-5,-12)
Putting the values in the formula

Hence,
It is slope of a line which is 4
