Slope = (y2 - y1)/(x2 - x1) = (-2 - 3)/(6 - (-4)) = -5/10 = -1/2.

Answer: B

Formula of slope of a line that passes through points \((x_1,y_1)\) and \((x_2,y_2)\) = \(\frac {y_2 - y_1}{x_2 - x_1}\)
Therefore slope = \(\frac {(-2) - 3}{6 - (-4)}\) = \(\frac {-5}{10}\) = \(-\frac {1}{2}\)

Hence the answer is B.
