Answer:
3
Step-by-step explanation:
For it to be a linear function, then it obeys the general form of a liner equation which is y = mx + c
Where m represents the slope and c represents the y intercept 
Now let’s take the last point on the table;
and substitute the values of x and y;
we have;
10 = 2m + c. ••••••••(i)
let’s take the second to the last;
7 = m + c ••••••••••(ii)
So let’s solve both equations simultaneously 
Just subtract second from first directly
This gives m = 3 
 
        
             
        
        
        
3 1/2 ÷ 1 1/4
7/2 ÷ 5/4
7/2 · 4/5
28/10

What is diffrentiation?
- A technique for determining a function's derivative is differentiation.
- A technique for determining a function's derivative is differentiation. Mathematicians use a procedure called differentiation to determine a function's instantaneous rate of variation based on a particular variables. The most typical illustration is velocity, which is the rate at which a distance changes in relation to time.
- In mathematics, differentiation is used to determine change rates.
