Math Problem Statement

Determine the slope of the line shown in the graph provided.

Solution

The image shows a graph with a line passing through points on a coordinate plane. We need to determine the slope of the line.

To find the slope of a line, we use the formula: slope=ΔyΔx=y2y1x2x1\text{slope} = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1} where (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) are two points on the line.

Step-by-Step Solution

  1. Identify two points on the line: Observing the graph, it looks like the line passes through (4,2)(4, -2) and (4,4)(-4, 4).
  2. Calculate Δy\Delta y and Δx\Delta x:
    • Δy=4(2)=6\Delta y = 4 - (-2) = 6
    • Δx=44=8\Delta x = -4 - 4 = -8
  3. Find the slope: slope=ΔyΔx=68=34\text{slope} = \frac{\Delta y}{\Delta x} = \frac{6}{-8} = -\frac{3}{4}

Conclusion

The slope of the line is 34-\frac{3}{4}.

Here are some additional questions you might explore:

  1. What does a negative slope indicate about the direction of a line?
  2. How would the slope change if the line were steeper?
  3. What is the slope of a horizontal line, and why?
  4. What is the slope of a vertical line, and why?
  5. How can you find the y-intercept of a line from its graph?

Tip: To quickly check a slope on a graph, count the "rise" and "run" between two clear points on the line.
