Question

If the line 2x+3y-4 =0 is perpendicular to 3x-ay +5 =0, then find 'a'

Answer 1

Answer:

Step-by-step explanation:

if the two lines are ⊥  than the lines would intersect at only at point.

∴ the lines have a unique solution represented as a1/a2 ≠b1/b2

⇒ 2/3 ≠-3/a and hence a≠ -9/2

i.e. a can take any value other than -9/2
