Answer

The function \( f(x) = 5x - 6 \) is a straight line with a slope of 5 and a y-intercept at -6. It crosses the x-axis at \( \frac{6}{5} \).

Solution

The given linear equation is \( f(x) = 5x - 6 \). ### Known Conditions: - This is a linear function where: - The slope \( m = 5 \) - The y-intercept \( b = -6 \) ### Steps to Analyze the Function: 1. **Identify the Slope and Y-Intercept:** - The slope indicates that for every unit increase in \( x \), \( f(x) \) increases by 5. - The y-intercept tells us that the function crosses the y-axis at \( (0, -6) \). 2. **Determine the Function's Features:** - The function is linear, meaning it will graph as a straight line. - It has no maximum or minimum values since it extends infinitely in both directions. 3. **Find the x-Intercept:** - To find the x-intercept, set \( f(x) = 0 \): \[ 0 = 5x - 6 \] - Solve for \( x \): \[ 5x = 6 \implies x = \frac{6}{5} \] 4. **Graph the Function:** - The graph will have a slope of 5 and will cross the y-axis at -6 and the x-axis at \( \left(\frac{6}{5}, 0\right) \). If you need further analysis or specific calculations related to this function, please let me know!

Bonus Knowledge

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!
