Answer 2

Answer:

The co-ordinates of point A on the number line is 1. Now, there will be two points, one on the left of point A and the other on the right of point A on the number line which are at a distance of 7 units from point A.

Let the point C is on the right of point A and point B is on the left of point A each at a distance of 7 units from point A.The co-ordinate of point C will be larger and co-ordinate of point B will be smaller in comparison to the co-ordinate of point A

Now, d(A, C) = 7

So, co-ordinate of C − co-ordinate of A=7

Co-ordinate of C=7+co-ordinate of A=7+1=8

Also, d(B, A) = 7

So, co-ordinate of A − co-ordinate of B=7

∴ co-ordinate of B = co-ordinate of A − 7 = 1 − 7 = −6

Hence, the co-ordinates of the required points on the number line which are at a distance of 7 units from the point A are 8 and −6.
