Control the visibility of the parts of a piecewise function in plot with pushbutton

Hallo,

I have a piecewise function such:

x=0:1:10;

s1=(x>=0 & x<=5);
s2=(x>5 & x<=10);

y(s1)=2.*x(s1)+5;
y(s2)=-2.*x(s2)+25;

plot(x,y)

and I need to control the visibility of its two parts. If I push the button a part disappears. If I push it back appears. How can I do that?

Thank you.
