which of the following sets of ordered pairs does not satisfy a linear function? a. (2,5), 4,9), (6,13), (7,15), (9,17) b. (2,5), (3,7), (4,9), (5,11), (6,13) c. (2,6), (4,8), (6,10), (8,12), (10,14) d. (2,6), (3,9), (4,12), (5,15), (6,18)

a. (2,5), (4,9), (6,13), (7,15), (9,17)

Step-by-step explanation:

slope = (y2-y1) / (x2-x1)

a. (2,5), (4,9), (6,13), (7,15), (9,17)

m = (9-5) / (4-2) = 4/2 = 2 an increase in 2 y for every 1 x

from 7 to 9 is an increase of 2 in the x direction so we should increase 4 in the y direction (15 to 17 is an increase of only 2)

This is not a linear function

b. (2,5), (3,7), (4,9), (5,11), (6,13)

c. (2,6), (4,8), (6,10), (8,12), (10,14)

d. (2,6), (3,9), (4,12), (5,15), (6,18)
