Who are real life Heroes......

Heroic Stories do not have to be about life-and-death struggles! In fact, most aren't. Heroes aren't just people who dive into rivers to save others: they're regular people who go out of their way to help someone else without expecting something in return. They're just very very busy people who still have time to help someone else!

  1. (Q.5) If a, b, c are in A.P., then prove that the straight line ax + by + c = 0 will always pass through the point (1,- 2). (2 marks)


    Ans ->

    => b-a=c-b
    =>2b=a+c ------ [i]

    =>Putting The Value of (x,y) in the Equation ax + by + c = 0 >> so, a-2b+c=0
    = 2b=a+c
    = using [i] 2b=a+c
    = so, a+c=a+c = 0
    Hence Proved
