Understanding Ordered Pairs and Equations

The video tutorial explains how to determine if an ordered pair is a solution to a given equation. It starts by clarifying the concept of ordered pairs and their role in equations. The tutorial then tests two ordered pairs by substituting them into the equation, showing step-by-step calculations. The first pair does not satisfy the equation, while the second pair does, demonstrating the process of verifying solutions.

What is the equation we are trying to solve with ordered pairs?

• -3x - y = 6

• 3x + y = 6

• -3x + y = 6

• 3x - y = 6
