Which formula could be used to find an objects velocity on a position vs time graph?

• d / t
• t / d
• m / v
• y₂ - y₁ / x₂ - x₁

On a distance vs time graph... a downhill slope (to the right) indicates...

• the object is speeding up.
• the object is slowing down.
• the object is moving away from the origin.
• the object is moving towards the origin.
