How can you find average velocity from a position-time graph? How can you find instantaneous velocity from a position-time graph?
Any help is appreciated!

A position-time graph, also known as a displacement-time graph, is a visual representation of an object's position or displacement over time. It shows how an object's position changes as time passes.
A position-time graph shows an object's position or displacement over time, while a velocity-time graph shows an object's velocity or speed over time. In other words, a position-time graph tells us where an object is located at a given time, while a velocity-time graph tells us how fast the object is moving at a given time.
The slope of a position-time graph represents the object's velocity. A steeper slope means a higher velocity, while a flatter slope means a lower velocity. The units of the slope are typically in meters per second (m/s).
To determine an object's average velocity from a position-time graph, we can calculate the slope of a straight line connecting two points on the graph. The average velocity will be the change in position (vertical axis) divided by the change in time (horizontal axis).
A horizontal line on a position-time graph represents that the object is not moving, or its velocity is zero. This is because the position is not changing over time, indicating that the object is at rest.
