co-ordinates of points and distorce- Observe the number line given below. + co-ordinate: Here, the point D on the Denotes the number 1 is the co-ordinator of Doint. To find the Distance between tee Dents, consider their co-ordinotes and substract the smaller co-ordnom from the layer, The Distance between Doints and is denoted by a This is the same as e CEO), ie the length of the segment Let's find dCA, B): The co-ordinate of AA is-s and that of B is-3 as - 3 - 5 ,,d (A,B) = -3-(-5) --3+S The distance between two points is obtained by subtracting smaller co-ordinate from the layer co-ordinate, The distance between any two points is a non- negative Peal number.
