Remember, speed is the absolute value. So if your velocity goes from zero to negative one meters per second, your speed just went from zero to one meter per second. So we're slowing down here, and we're speeding up here, but right at this moment, neither is happening. We are neither speeding up nor slowing down. Now what about this point? Here, the slope of our velocity time graph, or the slope of the tangent line, is still negative, so our velocity is still decreasing. But what about speed?
