Attached is example of equation of a plane 3D.  
I would know how to determine the range of values for x, y and z respectively.  
Thanks and Regards

You wonder what the actual range of the picture is? Here is a way:

```
ContourPlot3D[5 x - 2 y + 7 z == 15,
 {x, -7, 7}, {y, -7, 7}, {z, -7, 10},
 Mesh -> None, ContourStyle -> Yellow,
 AspectRatio -> 1]
AbsoluteOptions[%, PlotRange]

```

You don’t like the range of the picture, and need to make your own? Here:

```
ContourPlot3D[5 x - 2 y + 7 z == 15,
 {x, -7, 7}, {y, -7, 7}, {z, -7, 10},
 Mesh -> None, ContourStyle -> Yellow,
 AspectRatio -> 1,
 PlotRange -> {{-10, 10}, {-10, 10}, {-10, 10}}]

```

Thanks  
How to determine the {x, -7, 7}, {y, -7, 7}, {z, -7, 10} ?

Thanks

Sorry, I don’t understand your question.
