Did you know that linear equations like \( f(x) = 5x - 6 \) can be represented graphically as a straight line? The slope of this line (5) indicates that for every unit increase in \( x \), \( f(x) \) increases by 5 units! The y-intercept is -6, which means the line intercepts the y-axis at the point (0, -6). This gives you a quick visual of how steep the line is and where it crosses the y-axis. In real-world applications, linear equations are often used to model relationships between variables. For example, if you were analyzing your weekly spending on snacks, you could use a linear equation to describe how much more you spend for each extra snack you buy. In this scenario, \( 5x - 6 \) could represent your total spending, where \( x \) is the number of snacks, providing a simple yet effective way to manage your budget!
