Apply Ariom 2 to find the unique fold (line) that places p₁ = (1,4) on to p2 = (3, 1).

Check your answer by plotting the two points in Desmos, plot also the fold line. You could even

print this out and make sure it works. (With only one fold the result is just a folded piece of paper,

not an origami crane or even a hat, but check that the two points are placed on top of each other.)
