How do I specify - in the example below - the y-labels individually for the two subplots?

I am having a hard time finding just a single example of subplot where the xlabel and ylabel have been used/demonstrated.

Tnx!!!

```
using Plots
gr(size=(400,400), legend= false)
x = 0:100
y = x.^2
z = sqrt.(x)
l = @layout([a;b])
plot(x, [y z], layout=l, xlabel="x", ylabel="y")
```
