Answer:
a = Negative one-fifth
Step-by-step explanation:
The given equation is :

We need to find the value of a.
Subtract 2/5 from both sides.

So, the correct answer is Negative one-fifth. Hence, the correct option is (b).
Answer:
(-5,9+√8)
Step-by-step explanation:
There are two ways in which you can find a point that lies in the circle. One of them is to do y the subject of the formula, and another one is to determine the center of the circumference, and with the information of the radius, you can sum this value upward or downward.
the general equation of a circle is:

with center at (h,k)
you have the following equation:

Then, the center is (-5,9)
if you sum the value of the radius in one of the fourth directions (up, down, left, right), for example upward you have

Then, one point that lies in the circle is (-5,9+√8)
