20. When the slope of a D-T graph is positive (i.e. moving upwards), the object is moving __ from the reference point. __

## Step 1<br />The problem refers to a Displacement-Time (D-T) graph. In such a graph, the slope represents the velocity of the object. <br /><br />## Step 2<br />When the slope of the graph is positive, it indicates that the velocity of the object is positive. <br /><br />## Step 3<br />A positive velocity means that the object is moving in the positive direction, which is usually considered as moving away from the reference point.
