Determining Solutions to Equations Using Graphs

In this video, the teacher explains how to use a graph to determine if a coordinate pair is a solution to an equation. They demonstrate this by graphing different equations and showing how to identify the points that satisfy the equation. By connecting the points on the graph, they show how the shape of the graph represents all the solutions to the equation. The teacher also mentions that algebra can be used as an additional method to check if a coordinate pair is a solution.
