Hello, everyone. How can I plot in the same figure a continuous function and a point in Wolfram|Alpha? I tried with:

(x-0.1)*(y-0.9)=1 and Graphics[Point[{0, 0}]]

but it doesn't work in Wolfram|Alpha.

Thank you in advance.

You may fake it this way:

plot ((x - 1/10)*(y - 9/10) - 1) (x^2 + y^2-1/150) == 0

Hello @Gianluca Gorni , can you explain me how can I specify the points I want to plot please? For example P1=(0,0), P2=(1,2).

You can try something like this:

plot ((x - 1/10)*(y - 9/10) - 1) (x^2 + y^2-1/150) ((x-1)^2 + (y-2)^2 - 1/150) == 0 for x between -5 and 5

However, I would suggest using the Wolfram Development Platform for this kind of tasks, instead of Wolfram|Alpha.
