The answer is a. 1/7 The length of QR is 3 sqrt(2) which means half of that is where the median intersects. Since the triangle formed is a right triangle with legs that are equal. The vertex angles are 45°, we can get the coordinates of the point of intersection which is (4.5,3.5). So, m (slope) = (3.5-3)/(4.5-1) = 1/7
