### plotting points

How can I show points that I get as the result in line 11? I have that two circles, but I do not know how to get points on the graph.

var('x, y') ft = (x+1)^2-(y)^2-1 f=circle((-1,0), 1) p = plot(f,-5,5, thickness=2) @interact def _(r=(1..4)): g = circle((1,0), r) pt = plot(g,-5, 5, color='green', thickness=2) gt= (x-1)^2+ y^2-r pot = solve([ft,gt], x, y) html('$tocke=\;%s$'%latex(pot)) show( dot + p + pt, ymin = -5, ymax = 4)
