Hi there!

The standard form of the equation of a circle is:
(x - a) {}^{2} + (y - b) {}^{2} = r {}^{2}

With (a, b) representing the centre and r representing the radius of the circle.
Since the centre of the circle is (4, -3) and the radius is 3, we get the following equation:

(x - 4) {}^{2} + (y + 3) {}^{2} = 9

-2x-4y = 2
-2x-4y+4y = 2+4y
-2x=4y+2

Divided by 2:
-2x/-2 = 4y +2/ -2
Answer: x=-2y-1

3x +4y =8
3x + 4y = -4y = 8+-4y
3x= -4y +8
Divided by 3
3x/3 = -4y + 8/3
x=-4/3y + 8/3
