  1. Exploring Slope

  2. Movie Clip Try to find as many examples of slope as you can in the following clip. Be prepared to share your ideas.

  3. Investigation 1. • Graph y = x, y = 2x, and y = 3x on one coordinate plane. • How does the graph of y = kx change as k, the coefficient of x, increases?

  4. Investigation (continued) • a. Graph y = x and y = -x on the same coordinate plane. b. How are the graphs of y = x and y= -x alike? Different?

  5. Slope Slope – the steepness of a line. Slope = rise = subtract the y’s run subtract the x’s

  6. Example 1 Find the slope of each line. a)

  7. b)

  8. Example 2 Find the slope of the line through C(-2, 6) and D(4, 3).

  9. Example 3 Find the slope of each line. a)

  10. b)
