Начертите координатный луч и отметьте на нем точки соответствующие числам 3,6,,8,10

Sure, I will draw a coordinate axis for you. Let's assume it is a horizontal axis.

On the horizontal axis, we will label the points corresponding to the numbers you mentioned: 3, 6, 8, and 10.

Here is the coordinate axis with the marked points:

              |  3  |___|___| 6  |___|___| 8  |___|___| 10 |
              -------------------------------------------
                            <- X Axis ->

Please note that the distance between each of the marked points is equal, representing an interval of 2 units.
