One point on a line is given the coordinate 5.3. A second point on the line has a coordinate of 8.7.

The distance between these points is __________ units.

Respuesta :

Answer:

3.2

Step-by-step explanation:

The distance formula  on a number line is

d= x2-x1

d= 8.7-5.3 =3.2

Answer: The distance between these points is 5 units.

Step-by-step explanation:

We know that by Distance formula , the distance between two points (a,b) and (c,d) is given by :-

[tex]D=\sqrt{(d-b)^2+(c-a)^2}[/tex]

The given points = (5,3) and (8,7)

The distance between theses points will be :

[tex]D=\sqrt{(7-3)^2+(8-5)^2}\\\\\Rightarrow\ D=\sqrt{(4)^2+(3)^2}\\\\\Rightarrow\ D=\sqrt{16+9}\\\\\Rightarrow\ D=\sqrt{25}=\pm5[/tex]

Since , Distance is always positive , it means the distance between the given points is 5 units.
