Understanding the graph of a linear function is really important. It helps us see how two things are related. The graph looks like a straight line, and it gives us some important information about that relationship.
Slope: The slope is how steep the line is. It shows us how much one variable changes when the other one changes. If the slope goes up, it means that when one variable increases, the other one does too. If the slope goes down, the two variables move in opposite directions.
Y-intercept: The y-intercept is where the line crosses the y-axis. This point tells us the value of the dependent variable when the independent variable is zero. This point helps us understand how the function starts.
Domain and Range: The graph also shows us what values are allowed for the independent variable (domain) and what values we get for the dependent variable (range). This is important for knowing the limits of the function.
Predictive Power: By looking at the graph, we can make educated guesses about unknown values. For instance, if we pick a number on the x-axis, we can find the matching y-value.
Knowing these parts is really helpful in algebra. They help us see how math works in real life—like in budgeting, looking at trends, or understanding science. So, when students learn to interpret the graph of a linear function, they gain the skills to understand and use math concepts better.
