How can i make Desmos equations only visible, if a variable is less than 0?

Question

Say i have some variable k that I can change, and an equation. How do I make the equation invisible, if, for example, k<0 is true?

I tried to append {k<0} to the equation, which just made the equation invisible at all values of k.

What do you mean by "invisible" ? Do you mean specifying a domain of definition ? — Jean Marie, Apr 22 '23 at 09:05
@JeanMarie I just want an equation to not show up on the graph in some way when k<0 is true. — danik0011, Apr 22 '23 at 09:16
I tried it in desmos on my laptop, with the example $y=kx$ {$k>1$}, and it seems to work fine. — Zoe Allen, Apr 22 '23 at 09:17
@JeanMarie @ZoeAllen also, the variable k is not related to the equation in any way. It is not mentioned in the equation. — danik0011, Apr 22 '23 at 09:17
$f\left(x\right)=\left{x<0:x\right}$ defines $y=x$ on the domain of definition on $(-\infty,0]$ — Jean Marie, Apr 22 '23 at 09:18
I tried it with $y=x$ {$k>1$} as well, which also works fine. — Zoe Allen, Apr 22 '23 at 09:20
should i just give you the link to my graph and tell what i'm trying to make there? — danik0011, Apr 22 '23 at 09:21

It should work with curly braces, for example: $$x^2\left\{x > 0\right\}$$
