Answer:
The length of this line is of 5 units.
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this question:
The length of the line is the distance between these two points. So
[tex]d = \sqrt{(5-2)^2 + (9-5)^2} = \sqrt{3^2+4^2} = \sqrt{25} = 5[/tex]
The length of this line is of 5 units.
