Consider the point. (1, 4, 5) What is the projection of the point on the xy-plane?

Given :

A point ( 1 ,4 ,5 ).

To Find :

The projection of the point on the xy-plane .

Solution :

Now , to find projection of a point in a plane in a plane we need to replace the coordinate of that remaining axis which is not in the plane .

Here , the plane given is xy-plane . So , remaining axis is z .

So , we replace coordinate of z =0 .

Therefore ,  the projection of the point ( 1 ,4 ,5 ) on the xy-plane is ( 1 ,4 ,0 ) .

Hence , this is the required solution .

hi! i think the answer is 1/2 : )

i believe that the answer is

b. y-1=-2(x-4)

hope this !
