ANSWER

y = x + 8

EXPLANATION

We can see that, the difference in y-values from the table is 3

Also the difference in the x-values is 3.

Hence the slope is

m =  \frac{3}{3}  = 1

Let y=mx +c be function equation.

We put m=1 to get,

y = x + c

From the table when x=2, y=10.

This implies that,

10 = 2 + c

c = 10 - 2 = 8

Hence the function equation is

y = x + 8
