Given a straight line BD where point E lies on it.
Find the coordinates of D given that and the equation of the line BD is
Was that the original wording of the problem?
It's written very badly.
Here's a back-door approach . . .Given points and
Find the coordinates of point D so that
Code:½ B(½,3)o - + \ : d \ : 2 \: E(1,1)o - - - + \ : \ : \ : 3d \ : \ : \ : \: D o
Going from to , we moved unit right and 2 units down.
. . And we moved a diagonal distance
Going from to , we want to move a diagonal distance
. . Hence, we must triple our previous moves.
From , we move units right and 6 units down.
Therefore, point is: .
