Question 749837: I'M SO LOST PLEASE HELP!
Point A is the origin. Find the coordinates of the two points that are 5 units distant from A, and have x-coordinates of +3. (Hint: make a sketch. The two points fall on the line x=5, and therefore have coordinates (5,y) where y is unknown. Use the distance formula, suitably rearranged.)

Point A is the origin. Find the coordinates of the two points that are 5 units distant from A, and have x-coordinates of +3.
----------------
A is (0,0)
----
d%5E2+=+diffy%5E2+%2B+diffx%5E2+=+25
diffx = 3
----
3%5E2+%2B+%28y-0%29%5E2+=+25
y%5E2+=+16
y = -4, +4
--> (3,-4) and (3,4)
