Essential and guiding questions:
- Is there anything unique about this table? Do we have to keep the table as it is or could we change the way it looks and still do this problem?
- Are we sure our graph should be a line? How do we know? What is the significance of the point where the line crossed the y axis? The x‐ axis? (Show both possible graphs) How can these graphs be correct, yet one has positive slope and one has negative?
- Was the speed you found positive or negative? What is the significance of this? When you are riding in your car can your speed be negative?
- Is this the only possible equation for the line? Is there a simpler one? What is the significance of the y‐3 in the equation? The ‐52? The x – 208? Did it matter which graph we refer to as to if the equation is correct?
