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

In the image, we have a line on the coordinate plane. To calculate the slope of the line, we will apply the formula:

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

First, we need two points on the line. From the graph, it appears the line passes through points (8,8)(-8, 8) and (4,4)(4, -4).

Using these points:

  • (x1,y1)=(8,8)(x_1, y_1) = (-8, 8)
  • (x2,y2)=(4,4)(x_2, y_2) = (4, -4)

Now, we calculate the rise (change in yy) and run (change in xx):

rise=y2y1=48=12\text{rise} = y_2 - y_1 = -4 - 8 = -12 run=x2x1=4(8)=4+8=12\text{run} = x_2 - x_1 = 4 - (-8) = 4 + 8 = 12

Thus, the slope of the line is:

slope=1212=1\text{slope} = \frac{-12}{12} = -1

So, the slope of the line in simplest form is 1-1.

Here are some related questions:

  1. How do you calculate the slope from two points?
  2. What does a slope of 1-1 mean in terms of the direction of the line?
  3. Can the slope formula be applied to vertical or horizontal lines?
  4. How can you find the slope from a graph without exact points?
  5. What would the slope be if the line was steeper or flatter?

Tip: When calculating slope, remember that positive slopes rise as you move right, while negative slopes fall.
