Question

If the coordinates A and B are 1 and 7 respectively ,then find d(A,B)

Answer 1

Answer:

Step-by-step explanation:

Given,

A = 1 & B = 7

So, d(A, B) = d(1, 7)

Answer 2

If the coordinates of points A and B on a number line are 1 and 7 respectively, then the distance d(A, B) is __________ units.

For having coordinates of 7 and 1, the distance d(A, B) is going to be 6 units.

Given:

The coordinates of points A and B on a number line are 1 and 7 respectively.

To Find:

The distance d(A, B).

Solution:

Here two points are 7 and 1.

In a number line, we apply the distance formula as A-B units.

Thus,

if A = 7

and B =1

Then, we can write distance d(A,B) = 7-1 = 6 units

The distance formula in the case of the X-Y plane is,

(x₂ - x₁)/(y₂ - y₁)

where,

(x₁,y₁), and (x₂,y₂) are two points on the X-Y plane.

But here it is only a number line or in one direction.

Thus,

For having coordinates of 7 and 1, the distance d(A, B) is going to be 6 units.
