Final Answer:

The equation that models the line passing through the points (-1, 4) and (3, 2) is
\(y - 2 = -(1)/(2)(x - 3)\). thus option A is correct.

Step-by-step explanation:

To determine the equation of the line passing through the given points (-1, 4) and (3, 2), we can use the point-slope form of a linear equation, which is
\(y - y_1 = m(x - x_1)\), where
\((x_1, y_1)\) are the coordinates of a point on the line, and (m) is the slope. The slope (m) can be calculated using the formula
\(m = (y_2 - y_1)/(x_2 - x_1)\) with the given points (-1, 4) and (3, 2). Substituting these values, we find that
\(m = -(1)/(2)\). Choosing one of the points, say (-1, 4), we substitute the values into the point-slope form, resulting in the equation
\(y - 2 = -(1)/(2)(x - 3)\).

Now, let's check each given option. Option (A) matches the derived equation,
\(y - 2 = -(1)/(2)(x - 3)\). Options (B), (C), and (D) have different slopes or intercepts, and thus, they do not represent the line passing through the specified points.

In conclusion, the correct equation is (A)
\(y - 2 = -(1)/(2)(x - 3)\), as it accurately models the line passing through the given points (-1, 4) and (3, 2).
