To find a line that is perpendicular to \( y = -3x + 6 \), we need to determine the slope of the given line first. The slope is -3, so the perpendicular slope will be the negative reciprocal, which is \( \frac{1}{3} \). Now, we need to use the point-slope form of the line equation, \( y - y_1 = m(x - x_1) \), where \( (x_1, y_1) \) is \( (3, 2) \). Using the slope \( \frac{1}{3} \) and the point \( (3, 2) \): \[ y - 2 = \frac{1}{3}(x - 3) \] Simplifying this will give us the equation of our desired line: \[ y = \frac{1}{3}x + 1 \] Therefore, the correct answer is B. \( y=\frac{1}{3} x+1 \).
