Understanding Solutions to Linear Equations

The video tutorial explains how to find solutions to the linear equation X - 4Y = 6. It demonstrates the process of substituting values for X or Y to find ordered pairs that satisfy the equation. The tutorial provides four solutions, verifies them graphically, and emphasizes the infinite number of solutions possible for linear equations in two variables.

What is an ordered pair in the context of a linear equation?

• A pair of numbers that do not satisfy the equation

• A pair of numbers that satisfy the equation

• A pair of numbers that are always negative

• A pair of numbers that are always positive
