Suppose this line represents a walking situation in which youre using a motion sensor to measure distance. The x-axis shows time and the y-axis shows distance from the sensor. a. Is the slope positive, negative, zero, or undefined? Explain. b. What is the real-world meaning of the x- and y-intercepts? c. If the line extended into Quadrant II, what could that mean? If the line extended into Quadrant IV?
