To find the slope of the line passing through the points \((-9, 6)\) and \((-3, 9)\), we use the slope formula:<br /><br />\[<br />m = \frac{y_2 - y_1}{x_2 - x_1}<br />\]<br /><br />Here, \((x_1, y_1) = (-9, 6)\) and \((x_2, y_2) = (-3, 9)\). Plugging these values into the formula, we get:<br /><br />\[<br />m = \frac{9 - 6}{-3 - (-9)} = \frac{3}{-3 + 9} = \frac{3}{6} = \frac{1}{2}<br />\]<br /><br />So, the slope of the line is \(\frac{1}{2}\).<br /><br />The correct answer is:<br />A \(\frac{1}{2}\)
