The equation in point-slope form is given by:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is a point on the line.

In this case, the slope is -1/2 and the point is (-3, 12).

Substituting these values into the equation, we get:

y - 12 = -1/2(x - (-3))

Simplifying further:

y - 12 = -1/2(x + 3)

Therefore, the correct equation in point-slope form is:

y - 12 = -1/2(x + 3)

So, the answer is B.
