Answer 1

firstly let's work out the slope :).
So we'll use two points from the table:
(0, 5 ) and (1, 7)
Plug it into the slope formula:
m (slope) = ( y2 - y1) / (x2 - x1)

Answer 2

seems a linear function
who's slope is 2
the fact that the slope is not changing means we are dealing with a linear function
