Plots are objects that can be added, so you can first create the plot of your function:

```
sage: F = plot3d(lambda x,y: x^2+y^2, [-2,2], [-2,2])
```

Then the plot of the plane $x=1$

```
sage: P = implicit_plot3d(lambda x,y,z: x-1, (-2,2), (-2,2), (-2,8))
```

Then you can add them on a common plot:

```
sage: F+P
```

thanks a lot, didn't know could use lambda to pass functions in sage (completely new to this package)
