- Distance is a measurement of how far a position or object is from another on a given path
- Example: The distance from Dallas to Little Rock is 319 miles on Interstate 30
- The distance between two points x2 and x1 on a number line is equal to the absolute value of the difference between the two points or |x2 – x1| = √(x2 – x1)²
- The distance between two points that form a line segment that is NOT parallel to the x or y axis on a coordinate plane can be found with the distance formula
