Assume this is function is a straight line, consider the equation of the straight line: 
To find the gradient of the equation, we use any two coordinates from the table. 

We substitute the value of m in the equation:

To find c, we use the leftover coordinates, (4,0) in the equation above:

Substitute this value of c in the equation to get the function:

the answer to your question there would be 12
