Step-by-step explanation:
Answer: First Option is correct.
Explanation:
Since we have given that
there are two points from which the line is passing through :

We have to use the two point slope form .
As we know the " Two point slope form" i.e.

Here,

So, our equation becomes,

Hence, First Option is correct.
The square of a binomial is a pattern you would do well to remember.
.. (x +y)^2 = x^2 +2xy +y^2
Your expression has x^2 = 25a^2, so x = 5a. It also has y^2 = (b^2)/4, so y = b/2.
then the middle term is
.. 2xy = 2(5a)(b/2) = 5ab
The trinomial is
.. 25a^2 +5ab +(1/4)b^2 = (5a +b/2)^2
