Question

the co-ordinate of point A on number line is 5. find the coordinalis of points on same number line which are 13 units away from A.

Answer 1

The coordinates of points on the same number line which is 13 units away from A can be 18 or -8.

As it is not specified in the question that the number is 13 units away from which side.

So we will consider both cases:

• Case1: On the right side.

To get the value of the coordinate on the right side we just add the given number with 13

SO the coordinate is

5+13 = 18

• Case2: On the left side.

To get the value of the coordinate on the left side we just the subtract 13 from the given number.

SO the coordinate is

5-13 = -8

Answer 2

Answer:

The coordinates of points on the same number line which is 13 units away from A can be 18 or -8.
