Answer:

the other extermity of diameter of circle is (3, 5)

The other extremity of diameter is (-3,-5)

b is the correct option.

Step-by-step explanation:

The given circle is

x^2+y^2-3x+8y-3=0

The general equation of a circle is

x^2+y^2+2gx+2fy+c=0

Comparing the given equation with this equation

2 g = - 3 = > g = -3/2

2f = 8 => f = 4

Therefore, the center of the equation is given by

(-g,-f)\\\\=(\frac{3}{2},-4)

Now, we know that center is the mid point of the two extremities of diameter.

Let the other  extremity of diameter is (x,y).

Thus, center is the midpoint of (x,y) and (6,-3)

Formula for midpoint is given by

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

Therefore, we have

\frac{x+6}{2}=\frac{3}{2}\\\\x+6=3\\\\x=-3

And

\frac{y-3}{2}=-4\\\\y-3=-8\\\\y=-5

Therefore, the other extremity of diameter is (-3,-5)
