The language of the graph:

• Axes: The y-axis represents the object's velocity, typically measured in meters per second (m/s). Positive values signify motion in the positive direction (usually rightward), while negative values indicate movement in the opposite direction (leftward). The x-axis depicts time, generally in seconds (s).

• The Slope Tells the Tale: The slope of the VT graph at any point corresponds to the object's acceleration at that specific time. A positive slope signifies positive acceleration, meaning the object is speeding up. Conversely, a negative slope indicates negative acceleration (deceleration), implying the object is slowing down. A horizontal line with a zero slope represents constant velocity, where the object maintains a steady speed.

Under the slop:
