You can put this solution on YOUR website! The following are coordinates of points in the xy-plane. Which of these points is nearest the origin?
--
The distance (x,y) is from (0,0) is d = sqrt(x^2+y^2)
------
a (0,-1)::::::::d = 1
b (0,1/2 )::::::d = sqrt(1/4) = 1/2
c (1/2, -1/2):::d = sqrt(1/4 + 1/4) = sqrt(1/2) = (1/2)sqrt(2)= 0.7071
d (1/2,1/2):::::d = sqrt(1/4 + 1/4) = sqrt(1/2) = (1/2)sqrt(2)
e (-1,-1):::::::d = sqrt(1 + 1) = sqrt(2)
