Answer:
D
Step-by-step explanation:
The graphed function rises 2 in y for each run of 1 in x
Therefor the slope is 2/1 = 2
-------------------------
A) goes up 6 for each run of 3
slope = 6/3 = 2
B) goes up 15 for each run of 3
slope = 15/3 = 5
C) this is in slope intercept for of y = mx + b
m is the slope = 6
D) this is in slope intercept for of y = mx + b
m is the slope = -4
-------------------------------------
only D has a slope less than 2
