For the equation y = 4x - 2, what ordered pair results when x = -1?
A(-1, -2)
B(-1, 6)
C(-1, -6)
D(-1, 2)
Answer & Solution
Correct answer: C. (-1, -6)
1. Substitute x = -1 into y = 4x - 2.
2. Compute 4 times -1, which is -4.
3. Simplify: -4 minus 2 equals -6, so y equals -6.
4. The ordered pair is (-1, -6).
