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

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
