Investigate how distance is measured between two points on a number line. Move points across negative and positive numbers in walking, temperature, and elevation contexts.

🎮 Try It
• Drag points A and B along the number line and watch the distance readout change.
• Click Swap x1/x2 to reverse which point comes first and see whether the distance formula value changes.
• Switch contexts between Distance, Temperature, and Elevation to see how number line distances apply to real measurements.

🎯 Your Mission
Place one point at a negative number and the other at a positive number so the total distance between them equals exactly 15 units.

🌍 Real-World Connection
Highway milestone markers allow drivers to find the exact distance between two exits simply by taking the difference between the two marker numbers.
