Answer:
- The value of

- The value of

Step-by-step explanation:
Let

and

As
is exactly divisible, so, the remainder is 0.
∴ 

As the R.H.S becomes 0 when
and
.
And
by substituting 

![25 + 20( \frac{\sqrt{5}}{\sqrt{2}} ) + a( \frac{\sqrt{5}}{\sqrt{2}}) +b =0...[A]](https://tex.z-dn.net/?f=25%20%2B%2020%28%20%5Cfrac%7B%5Csqrt%7B5%7D%7D%7B%5Csqrt%7B2%7D%7D%20%29%20%2B%20a%28%20%5Cfrac%7B%5Csqrt%7B5%7D%7D%7B%5Csqrt%7B2%7D%7D%29%20%2Bb%20%3D0...%5BA%5D)
by substituting 
![25 - 20( \frac{\sqrt{5}}{\sqrt{2}} ) - a( \frac{\sqrt{5}}{\sqrt{2}}) +b =0.....[B]](https://tex.z-dn.net/?f=25%20-%2020%28%20%5Cfrac%7B%5Csqrt%7B5%7D%7D%7B%5Csqrt%7B2%7D%7D%20%29%20-%20a%28%20%5Cfrac%7B%5Csqrt%7B5%7D%7D%7B%5Csqrt%7B2%7D%7D%29%20%2Bb%20%3D0.....%5BB%5D)
Adding Equation [A] and equation [B]

Answer:
C. 
Step-by-step explanation:
So we know that a vertical line is represented by
so we can already rule out two of the options. We also know that since the line runs vertically, all points will start with the same
coordinate. This means that the correct answer is
