Question

Find the distance between the point (-3, 4, -6) and its image in the XY-plane​

Answer 1

Answer:

12 units

Step-by-step explanation:

the given point is in VI octant ( -,+,-)

the image in XY plane in II octannt (-,+,+)

hence... the distance = 2 × z-cordinate

i,e,...|2 × 6| = 12 units

Note :

can use distance formule for (-3, 4, -6) & (-3, 4, +6)
