What does this graph represent.LINEAR FUNCTION, EXPONENTIAL FUNCTION, OR (neither)

LINEAR function  constant slope = 2

Step-by-step explanation:

We see points  (-3, -11),  (-2, -9),  (-1, -7),  (1, -3) , (2, -1)

slope:   m = (-9 - -11)/(-2 - -3) = 2/1

m = (-7 - -9)/(-1 - -2) = 2/1

m = (-3 - - 7)/(1 - -1) = 4/2 = 2

m = (-1 - -3)/(2 - 1) = 2/1 = 2

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.
