Detailed explanation-1: -If the velocity is constant, then the slope is constant (i.e., a straight line). If the velocity is changing, then the slope is changing (i.e., a curved line). If the velocity is positive, then the slope is positive (i.e., moving upwards and to the right). This very principle can be extended to any motion conceivable.
Detailed explanation-2: -The slope of a displacement-time graph gives the velocity. If the slope is positive, it indicates that the body is moving away from the reference or the starting point.
Detailed explanation-3: -If the line slopes upward from left to right, this means the object is speeding up. Its acceleration will be positive. If the line slopes downward from left to right on the graph, this means that the object is slowing down. Its acceleration will be negative.
Detailed explanation-4: -The slope of a distance versus time graph is velocity.
