**drwls**, Sunday, October 2, 2011 at 7:14amThe points on the circle that are the nearest and farthest from (4,5) will be the two points on the line that connects (4,5) with the center of the circle, located at (0,0). The equation of that line is

y = (5/4) x

Points on both the line and the circle must satisfy the equation

x^2 + (25/16)x^2 = 9

(41/16)x^2 = 9

x = + or - 12/sqrt41 = + or - 1.87409

y = (5/4)x = + or - 2.34261

Farthest point: (-1.87409, -2.3261)

Nearest point: (1.87409, 2.3261)
