A. (0.2,3.4)
B. (0.1,2.1)
C. (0.4,2.9)
D. (0.4,3.7)

C. (0.4,2.9)

Step-by-step explanation:

When x = .4 the y values are getting the closest to each other

Averaging the y values

(2.8 + 3)/2 = 2.9  is a good approximation to the solution

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
