Find the slope, if it exists, of the line containing the pair of points \( (6,-10) \) and \( (-8,-10) \). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The slope of the line is \( \square \). (Type an integer or a simplified fraction.) B. The slope is undefined.

To find the slope of the line through the points (6, -10) and (-8, -10), use the slope formula:   slope (m) = (y₂ - y₁) / (x₂ - x₁). Let (x₁, y₁) = (6, -10) and (x₂, y₂) = (-8, -10):   m = (-10 - (-10)) / (-8 - 6)   m = (0) / (-14)   m = 0 Thus, the slope of the line is 0, which corresponds to a horizontal line. Answer: A. The slope of the line is 0.
