Question

.Find the equation of projection in standard form on the plane 3x + 2y+ z= 0 of the line

3x− y + 2z − 1 = 0 = x+ 2y− z − 2. Show that the point (-1, 1, 1) lies on this projection .​

Answer 1

Step-by-step explanation:

3x+2y+z=0

ax+by+z=0

slope=coefficient of x/cofficent of y

-a/b

-3/2
