This activity is intended to supplement Algebra I, Chapter 7, Lesson 2.
Problem 1 - Solving for Two Unknowns
2. Use the above information to fill in the blank spaces.
The solution is the intersection point. Adjust the window so that you can see the intersection of the two lines.
4. How does this point compare with your solution from Question 3?
Record the rate of the boat in still water and the distance between the towns. Include units.
Problem 2 - Distance-time graph, explore slopes
To explore this situation graphically, we need to set up the graph.
Create a scatter plot of the data points.
Then press WINDOW and arrow to SETTINGS.
5. What does the slope of the line in the distance-time graph represent?
7. Algebraically solve the equation.
Problem 3 - Extension/Homework
Hint: Distances will add up to 160
