Exploring Slope Created by Sara Wheeler
Movie Clip Try to find as many examples of slope as you can in the following clip. Be prepared to share your ideas.
Investigation 1. a.Graph y = x, y = 2x, and y = 3x on one coordinate plane. b.How does the graph of y = kx change as k, the coefficient of x, increases?
Investigation (continued) 2.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?
xy=xy=2xy=3xy=-x 0 1 2
Slope Slope – the steepness of a line. Slope = rise = subtract the ys run subtract the xs
Example 1 Find the slope of each line. a)
Example 2 Find the slope of the line through C(-2, 6) and D(4, 3).
