Question 297573
Start at the origin (where the the x and y axis intersect)


Now move your pencil 1 unit to the right

We move 1 unit in this direction since the x-coordinate is 1 (its the first number of the pair)




{{{drawing(500,500,-6,6,-6,6,
grid(1),
blue(arc(0.5,0,1,2,0,180))
)}}}


Now go 1 unit up

We move 1 unit in this direction since the y-coordinate is 1 (its the second number of the pair)



{{{drawing(500,500,-6,6,-6,6,
grid(1),
blue(arc(0.5,0,1,2,0,180)),
green(arc(1,0.5,1,1,270,90))
)}}}


Plot a point where the pencil lands


{{{drawing(500,500,-6,6,-6,6,
grid(1),
circle(1,1,0.08),
circle(1,1,0.10),
blue(arc(0.5,0,1,2,0,180)),
green(arc(1,0.5,1,1,270,90))
)}}}


So here is the point (1,1)


{{{drawing(500,500,-6,6,-6,6,
grid(1),
circle(1,1,0.08),
circle(1,1,0.10)
)}}}



Note: The point (1,1) is in the first quadrant
