Question

x,-2 Co-ordinates of pair of points are given. Hence find the distance between given pair.

Answer 1

To find the distance between two points,we should subtracted both points.
let distance between these points be D.
D
$= x - ( - 2) \\ = x + 2$
the distance between these two points is x+2

Answer 2

********************†***************

The distance between points

lying on X-axis is the difference

between the X - coordinates .

***************************************

Here ,

x1 = x , x2 = -2

Required distance = | x2 - x1 |

= | -2 - x |

= | - ( 2 + x ) |
