What is the slope of the hypotenuses of the triangles in simplest form?

first-quadrant graph showing a ray through the origin and the points (5, 2), (10, 4), and (20, 8). two triangles each have hypotenuses with endpoints along the line, a vertical leg, and a horizontal leg. the first triangle has a hypotenuse with endpoints at (5, 2) and (10, 4). the second triangle has a hypotenuse with endpoints at (10, 4) and (20, 8).
