Math Problem Statement

Draw a line representing the 'rise' and a line representing the 'run' of the line. State the slope of the line in simplest form.

Solution

Let's analyze the graph from the image to solve the question.

The line appears to cross the y-axis at the point (0, -4) and another point on the line is (4, 2).

Step 1: Understanding Rise and Run

  • Rise: The vertical change between the two points.
  • Run: The horizontal change between the two points.

Between the points (0, -4) and (4, 2):

  • The rise (vertical change) is: 2(4)=62 - (-4) = 6
  • The run (horizontal change) is: 40=44 - 0 = 4

Step 2: Calculating the Slope

The slope mm is given by:

m=riserun=64m = \frac{\text{rise}}{\text{run}} = \frac{6}{4}

Simplifying the fraction:

m=32m = \frac{3}{2}

Thus, the slope of the line in its simplest form is 3/2.

5 Related Questions:

  1. How do you calculate the slope if the line passes through negative coordinates?
  2. What is the equation of the line that passes through the points (0, -4) and (4, 2)?
  3. How can you determine if a line is increasing or decreasing based on its slope?
  4. What happens to the slope of a line if the "rise" or "run" is negative?
  5. How does the slope of a horizontal line compare to the slope of a vertical line?

Tip:

When calculating the slope, always remember that if the rise or run is negative, the slope will be negative, indicating a downward-sloping line.
