Answer:
3
Step-by-step explanation:
The formula of to calculate slope of a linear function is
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope and so lets take any two points from the table to calculate the slope. Lets take,
(0 , 4) and (1 , 7) and lets plug it in the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{7-4}{1-0}\\\\m=3[/tex]
So the slope of the function is 3
