5. The number that corresponds to a point on a number line is called the _________ of the point. coordinate On the number line below, __ is the coordinate of point A. The coordinate of point B is __ Point C has coordinate 0 and is called the _____. -4 10 origin x 11-5-313579 -6 -4048-62106-2 A B C

6. x 11-5-313579 -6 -4048-62106-2 Look at the coordinate points below. What is the distance of segment DE? What is the distance of segment EF? What is the distance of segment DF? D E F You can also use number lines to find the distance between points, just like a ruler.

7. The distance between two points A and B on a number line is found by using the Distance Postulate. Postulate: Distance Postulate Points on a line are paired with real numbers, and the measure of the distance between two points is the positive difference of the corresponding numbers. measure = a – b B A a b
