No, because it does not have a constant rate of change
Step-by-step explanation:
look at the changes of the y values when going from one x value to the next.
x always changes by 1.
but y changes by +7, +5, +6.
the change rate is the ratio y/x.
as we can see, this changes in each interval.
so, the change rate is not constant.
but this is the deciding property of a linear function. as the name says, a linear function is a straight line. it has the same incline (= changes rate) everywhere on the line. otherwise it is not a straight line.
