The easiest way to explain this, if you have had calculus, is to say that changing slope on a distance-time graph is changing velocity.
Think of how distance per unit time is velocity (miles per hour or meters per second). If that is constant, then the slope of the line should be constant - you will travel the same number of miles or meters for each successive hour or second. If the velocity changes, then the slope of the line will change.

Which way is the slope changing? And which way are the axes?
If we presume that time is the horizontal axis, and the vertical axis shows the distance traveled in the given time, the slope at any point is the velocity. If the slope is increasing, more and more distance is traveled per unit time, and the velocity is increasing. If the slope is decreasing, the velocity is decreasing.
