Question

D the length of a line segments with the following endpoints. (2,5) (5,9)​

Answer 1

The length of this line is of 5 units.

Explanation:

Distance between two points:

Suppose that we have two points,
`(x_1,y_1)` and
`(x_2,y_2)`. The distance between them is given by:

`D = √((x_2-x_1)^2+(y_2-y_1)^2)`

In this question:

The length of the line is the distance between these two points. So

`d = √((5-2)^2 + (9-5)^2) = √(3^2+4^2) = √(25) = 5`

The length of this line is of 5 units.
