Question 134285
Start at the origin (where the the x and y axis intersect)


Now move your pencil 3 units to the right

We move 3 units in this direction since the x-coordinate is 3 (its the first number of the pair)

grid(1),
green(arc(0.5,0,1,2,0,180)),
green(arc(1.5,0,1,2,0,180)),
green(arc(2.5,0,1,2,0,180))
)}}}


Plot a point where the pencil lands


{{{drawing(500,500,-6,6,-6,6,
grid(1),
green(arc(0.5,0,1,2,0,180)),
green(arc(1.5,0,1,2,0,180)),
green(arc(2.5,0,1,2,0,180)),
circle(3,0,0.07),
circle(3,0,0.10)
)}}}



So this is the point (3,0)

circle(3,0,0.07),
