Question 91170
Start at the origin (where the the x and y axis intersect)


Now move your pencil 2 units up

We move 2 units in this direction since the y-coordinate is 2 (its the second number of the pair)

Plot a point where the pencil lands


{{{drawing(500,500,-6,6,-6,6,
grid(1),
green(arc(0,0.5,1,1,270,90)),
green(arc(0,1.5,1,1,270,90)),
circle(0,2,0.07),
circle(0,2,0.10)
)}}}



So this is the point (0,2)

circle(0,2,0.07),
