the table represents a linear function?

Answer: 5
Step-by-step explanation:
In the given picture we have a table representing two columns as x and y.
We know that the slope of the function is given by :-
[tex]k=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Using points (0,4) and (2,14) from the table , we get the slope of the function will be :-
[tex]k=\dfrac{14-4}{2-0}\\\\\\=\dfrac{10}{2}=5[/tex]
Therefore, the slope of the given function in the table = 5
