Answer 1

Check each choice by substituting its x-coordinate into y = 13x − 4 and see if you get the given y.

1. (3, 3): y = 13(3) − 4 = 39 − 4 = 35 ≠ 3
2. (9, 2): y = 13(9) − 4 = 117 − 4 = 113 ≠ 2
3. (6, −2): y = 13(6) − 4 = 78 − 4 = 74 ≠ −2
4. (−3, 7): y = 13(−3) − 4 = −39 − 4 = −43 ≠ 7

None of the given ordered pairs satisfy y = 13x − 4. (For reference, the correct y-values would be 35, 113, 74, and −43 respectively.)
