Math Problem Statement

The user provided an image showing a graph with a linear equation plotted on a coordinate plane. The equation appears to be y = -x + 5.

Solution

The image you provided shows a graph with a linear equation plotted on a coordinate plane. The red dashed line appears to be representing the linear equation y=x+5y = -x + 5.

Details of the Graph:

  1. Equation of the Line: The graph shows the line for the equation y=x+5y = -x + 5.

    • The slope of the line is 1-1, which indicates that for every unit increase in xx, yy decreases by 1 unit.
    • The y-intercept is 55, meaning the line crosses the y-axis at the point (0,5)(0, 5).
  2. Axes and Grid: The graph has both x and y axes clearly labeled, with a grid that allows for precise plotting of points.

  3. Line Characteristics:

    • The red dashed line appears to be straight, indicating a linear relationship.
    • The line crosses the x-axis at (5,0)(5, 0) and the y-axis at (0,5)(0, 5).
  4. Slope and Intercepts:

    • Slope (m): 1-1
    • Y-Intercept (b): 55
    • X-Intercept: 55 (where y=0y = 0, solve 0=x+50 = -x + 5 to get x=5x = 5).

Would you like a more detailed explanation of how to determine the slope, intercepts, or any other aspect of this equation?

Questions for Further Exploration:

  1. How do you determine the slope from a graph, and why is it important?
  2. What is the significance of the y-intercept in a linear equation?
  3. How would the graph change if the slope were positive?
  4. What is the relationship between the slope and the steepness of the line?
  5. Can you graph a line given only two points, and how does this compare to using the slope-intercept form?

Tip: When graphing a linear equation, always identify the slope and y-intercept first. This will make plotting the line easier and more accurate.
