Question 1132418: 1. The coordinates of the vertices of triangle abc are a(-2,1), b(4,-2) and c(1,8) respectively. If d(x,y) is the foot of the perpendicular from a to bc, find (A)an equation connecting x and y (B)the unit vector in the direction of bc

There is something wrong with the condition.

Notice that (x,y) are COORDINATES of the single point D.

Therefore, the assignment (A) "find an equation connecting x and y" MAKES NO SENSE.

I have very bad experience with some (unknown to me) visitors of this forum.


When I point them to their mistakes in their posts, they, instead to thank me, send their damnations to me.


Please do not follow that way . . .
