Beginnings of Slope

Explore slope and answer the questions below.
• Slide the m1 slider back and forth. After you observe how slope changes a graph, in your own words describe how slope changes the line of a graph. • Then, in your own words, describe what slope is. • Slide the b slider back and forth. After you observe how the y-intercept changes a graph, in your own words describe how the y-intercept changes the line of a graph. • With the two give points, determine what the slope of the line is. How did you come to this conclusion? Can you come up with a formula to find slope given two points? • Where do the two lines intersect? What does that intersection point mean?
