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 table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
