x^2 + y^2 - 6x - 4y - 12 = 0
x^2 - 6x + y^2 - 4y = 12
x^2 - 6x + 9 + y^2 - 4y + 4 = 12 + 9 + 4
(x - 3)^2 + (y - 2)^2 = 25

Look at the pic please

Since we know the slope of the line and a point that passes through it, we can use the <u>point-slope form formula</u> to determine the equation of the line.

Point slope form formula:

\text{ y - (y-coordinate of point) = slope(x - x-coordinate of point)}

We are given the following:

\bullet \ \ \text{Slope of line = -3}

\bullet \ \ \text{Line passes through (2, 4)} \implies \text{x-coordinate of point = 2; y-coordinate of point = 4}

When we substitute the values into the formula, we get;

<u />\implies y - (4) = -3(x - 2)}<u />

\implies \boxed{y - 4 = -3(x - 2) \ \ (\text{Option B})}

Therefore, option B is correct.
