Investigate Slope of a Line y = mx +b
1) Use the slider m to change the slope of the line y = mx + 4. 2) Move Points A and B. What do you notice about the slope of the line? 3) How would you calculate the slope m = rise / run? 4) What do you notice when m = 0? How would you describe the line? 5) What would the run be equal to for a vertical line? What would the slope be?
