Testing Solutions and Ordered Pairs

The video tutorial explains how to test solutions for a given equation by plugging in ordered pairs. It demonstrates the process using two points, showing how to determine if each point satisfies the equation. The first point is tested and found incorrect, while the second point is verified as correct, leading to the conclusion that the answer is option B.

What is the equation provided for testing solutions?

• 3x - y = 6

• -3x - y = 6

• -3x + y = 6

• 3x + y = 6
