To write an equation in point-slope form, we need a point on the line and the slope of the line.

The point-slope form is given by the equation:

\[ y - y_1 = m(x - x_1) \]

where \( m \) is the slope, and \( (x_1, y_1) \) is a point on the line.

Let's analyze the given options briefly:

\( y = -2(x - 4) \) is in slope-intercept form and not point-slope.
\( y − 4 = -2(x + 4) \) has a point \( (-4, 4) \) and slope \( -2 \).
\( y − 4 = -2(x − 4) \) has a point \( (4, 4) \) and slope \( -2 \).
\( y = 2(x + 2) \) is also in slope-intercept form.

If the slope of the line is \( -2 \) and it passes through the point \( (4, 4) \), the correct point-slope form would be:

\[ y - 4 = -2(x - 4) \]

Thus, the correct answer is:

\( y - 4 = -2(x - 4) \).
