Which table of values represents a linear function?
A

minus, 5−5 minus, 8−8
11 minus, 5−5
55 minus, 4−4
77 minus, 3−3
B
xx yy
00 66
33 33
66 00
99 minus, 3−3
C
xx yy
minus, 3−3 88
minus, 1−1 66
22 44
55 22
D
xx yy
11 77
55 11
77 minus, 2−2
99 minus, 4−4

Answer 1

B

Reason: In B each time x increases by 3, y decreases by 3 (slope = -1). The slopes between consecutive points in the other tables are not constant.
