★Answer★(34)

Given Here equation of two line :-

• 3x - 4y +7 = 0

=> y = (3x + 7 )/4

=> y = 3x/4 + 7/4 ...............(1)

And,

• ax + 9y + 1 =0

=> y = -(ax+1)/9

=> y = x(-a/9) +(-1/9).........(2)

Find here :-

• Value of a

__________________

Compare with general equation of line

• y = mx +c ............(3)

So, for line (1) ,

• m1 = 3/4 .

• m2 = (-a/9) .

____________________

But, we know,

If two line are perpendicular Then, slope of these will be = -1 ,

Or,

• m1 × m2 = -1

keep value of m1 and m2 ,

• (3/4) × (-a/9) = -1

• a = 9 × (4 / 3)

• a = 3 × 4

• a = 12

thus:-

• value of a = 9.
