Question

Which set of ordered pairs (x, y) could represent a linear function?

A = {(-6,9), (-3,6), (0,3), (4,0)}
B = {(1, 1), (2,3), (4,5), (5,7)}
C = {(-4,-4), (-2,-2), (1,0), (4,3)}
D = {(3,7), (5, 1), (6,-2), (7,-5)}

Answer 1

D, because the last three ordered pairs all have x values going up by 1 while the y value goes down by 3. On the first ordered pair its 7-3=4 then 4-3=1 to connect it the same goes for the x value you just gotta continue the pattern
