Hello

I write in SAGE

implicit_plot(y==1/2, (-1,1),(-1,1))

and it returns the graph of the line x=1/2. Why?

Sage does not guess the names of the variables (you could have been using any name). As your expression contains a single variable, it assumes that this is the first variable (what you would call "x"). To get what you want, use the more explicit syntax

sage: x = var('x')
sage: y = var('y')
sage: implicit_plot(y==1/2, (x,0,1), (y,0,1))
