Question

then a . (7) a FH1TR a13T 3quia Direction ratio of two parallel line will be.. hal-EIGA, TIUIA​

Answer 1

Answer:

As we know that the ratio of direction ratios of 2 parallel lines are equal So, for 1st line it is 4, - 3, - 1 and for 2nd line it is p + q, 1 + q, 2

Rightarrow 4 p+q = -1 2 1/2 * a * n * d * - 3/(1 + p) = - 1/2

p+q=-8 and -3 1+p = -1 2

Rightarrow p+q=-8....(1) and 1+p=6....(2) from (2) * p = 5

Rightarrow 4 p+q = -3 1+q = -1 2 substitute this value in (1) then q = - 8 - p Rightarrow q=-8-5 q = - 14
