Math Problem Statement
Graph the line with the equation y = -1/5x + 4.
Solution
Let's graph the given equation using the information from the image.
The equation is in the slope-intercept form , where:
- is the slope, indicating the line decreases by 1 unit vertically for every 5 units it moves horizontally.
- is the y-intercept, meaning the line crosses the y-axis at .
Steps to graph:
- Start at the y-intercept: Plot the point (0, 4) on the graph.
- Use the slope: From (0, 4), the slope tells us to move down 1 unit and right 5 units. Plot the point at (5, 3).
- Extend the line: Continue plotting points along the line by using the slope, or draw a straight line through the two points you plotted.

Here are 5 follow-up questions:
- What does the slope represent in this equation?
- How would the graph change if the slope were positive?
- Where does the line cross the x-axis?
- How would the graph look if the y-intercept were negative?
- What happens to the line if you change the slope to zero?
Tip: Always plot the y-intercept first when graphing lines in slope-intercept form!
