2. Using the same cyclist data (0, 12, 24, 24, 36, 48 km over 0-5 hours), what is the maximum distance shown?
3. Using the same cyclist data (0, 12, 24, 24, 36, 48 km over 0-5 hours), is the overall relationship increasing, decreasing, or constant?
4. Use \(y=3x-2\). What is the value of y when \(x=-2\)?
5. Use \(y=3x-2\). What is the correct ordered pair when \(x=1\)?
