Example: Evaluating Ordered Pairs for a Linear Equation
To evaluate whether an ordered pair is a solution to a linear equation such as , substitute the and values into the equation. For instance, testing the point yields , which simplifies to the true statement , meaning it is a solution. When plotted, this point lies exactly on the line representing the equation. Testing yields , which simplifies to the false statement , meaning it is not a solution. When plotted, this point does not lie on the line.
