Which set of ordered pairs (x, y) could represent a linear function?
A = {(3,4), (5,2), (7,0), (9,-2)}
B = {(-1,0), (0,3), (1,6), (2,8)}
C = {(-2,7), (1,3), (2, 1), (3,-1)}
D= {(0,3), 14, -3), (6,-6), (8,-8)}

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
