A steep slope on a phase change graph indicates a rapid change in temperature with respect to the amount of heat added or removed from a substance. During a phase change, such as melting or boiling, the temperature remains constant while the substance transitions between states of matter. The steep slope represents the energy required to overcome the intermolecular forces holding the particles together in a particular state.

A change in the slope of a location-time graph of an object indicates a change in the radial component of its speed.
Steep slope on a distance/time graph indicates high speed.
The slope of each point on the line on the graph is the rate of change at that point. If the graph is a straight line, then its slope is constant. If the graph is a curved line, then its slope changes.
A gradual change in the gradient (slope).
The slope will tell you how much change of Y to X >.
