Question

Under what condition do the planes bx - ay = n, cy - bz = l , az - cx = m intersect in a line? (A) a + b + c = 0 (B) a = b = c (C) al + bm + cn = 0 (D) l + m + n = 0

The planes bx - ay = n, cy - bz = l and az - cx = m intersect in a line, if al + bm + cn = 0.

Q. Under what condition do the planes bx - ay = n, cy - bz = l , az - cx = m intersect in a line?

a + b + c = 0

a = b = c

al + bm + cn = 0

l + m + n = 0

The planes $b x - a y = n, cy - b z = l$ and $a z - c x = m$
intersect in a line, if $a l + bm + c n = 0$ .

Q. Under what condition do the planes bx - ay = n, cy - bz = l , az - cx = m intersect in a line?

a + b + c = 0

a = b = c

al + bm + cn = 0

l + m + n = 0

The planes bx−ay=n,cy−bz=l and az−cx=m intersect in a line, if al+bm+cn=0.

The planes $b x - a y = n, cy - b z = l$ and $a z - c x = m$
intersect in a line, if $a l + bm + c n = 0$ .
