According to Hubble's law, the slope of the Hubble graph represents the rate of expansion of the universe. In a universe that is uniformly expanding more slowly than ours, the slope of the Hubble graph would be shallower because the velocity of galaxies moving away from each other would be lower. In other words, the distance between galaxies would be increasing at a slower rate, leading to a shallower slope in the Hubble graph.
