Graphs are super important for understanding linear equations. Let’s break down some key points:
Seeing the Data: Graphs show us what linear equations look like. This helps us understand them better.
Slope and Starting Point: The slope (we call it ) tells us how steep the line is or how fast it’s changing. The y-intercept (called ) shows where the line starts. You can remember this with the formula: .
Finding Solutions: Points on the line are the solutions to the equation. For example, in the equation , the point is one of those solutions.
Where They Meet: When we graph more than one equation, we can see where the lines cross. Those intersection points show us where the solutions match up.
