The correct answer is a.
You can find this by using each of the ordered pairs in the equation and seeing if the statements are true. The work for the a ordered pairs is below.
(-2, -14)
y = 7x
-14 = 7(-2)
-14 = -14
(3, 21)
y = 7x
21 = 7(3)
21 = 21
(-4, -28)
y = 7x
-28 = 7(-4)
-28 = -28
2) Inserting zeros at the right end of a decimal does not change its value
0.3 = 0.3000
4) To estimate the difference between 0.31 and 0.108, subtract 0.3.
22) 75.285 + 2 + 3.871 + 0.5 = 81.656
42) 0.01 - 0.0001 = 0.0099
50) 9 - 4.63 = 4.37
