Question

If a, c, b are direction ratios of line, then equation of line passing through a point
(X1. Yu, Zı) will take the form​

Answer 1

Answer:

a+2b+3c=0--- (1)

−3a+2b+5c=0---(2)

Solving (1) and (2), by cross multiplication, we get

10−6

a

=

−9−5

b

=

2+6

c

=k

⇒a=4k,b=−14k,c=8k

Thus, the required line passing through P(-1, 3, -2) and

having the direction ratios a=4k,b=−14k,c=8k is

4

x+1

=

−14

y−3

=

8

z+2

or

2

x+1

=

−7

y−3

=

4

z+2
