Math Problem Statement

Find the slope of the line shown in the graph.

Solution

To find the slope of the line shown in the graph, we can use the formula for the slope:

slope=y2y1x2x1\text{slope} = \frac{y_2 - y_1}{x_2 - x_1}

Here, we need to identify two points that lie on the line. From the graph, two convenient points are:

  • Point 1: (4,4)(-4, 4)
  • Point 2: (4,2)(4, -2)

Now, we can substitute these points into the slope formula:

slope=244(4)=68=34\text{slope} = \frac{-2 - 4}{4 - (-4)} = \frac{-6}{8} = -\frac{3}{4}

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

Here are 5 related questions for further practice:

  1. How do you interpret the negative slope in the context of a line?
  2. What happens to the slope of a line if it is horizontal or vertical?
  3. Can you find the equation of the line using the slope and a point?
  4. What is the slope of a line perpendicular to the given line?
  5. How would the slope change if the line was reflected over the y-axis?

Tip: When working with slope, remember that a negative slope indicates the line falls from left to right, while a positive slope indicates it rises from left to right.
