A(2, 11)
B(2, 4)
C(2, -9)
D(2, 9)
Answer & Solution
Correct answer: D. (2, 9)
1. Substitute x = 2 into y = 5x - 1.
2. Compute 5 times 2, which is 10.
3. Simplify: 10 minus 1 equals 9, so y equals 9.
4. The ordered pair is (2, 9), which is a third solution to y = 5x - 1 beyond the two already listed in the table.
