The point (2120) on the graph typically represents a specific coordinate where the x-value is 21 and the y-value is 20. This means that at x = 21, the corresponding output or value on the y-axis is 20. The significance of this point can vary depending on the context of the graph, such as indicating a data value, a solution to an equation, or a specific measurement in a given scenario.

We would have to see the graph.
Yes it does.
instantaneous acceleration* * * * *No it does not.The graph is a distance-time graph so the coordinates of a point on the graph represent the position (distance) at the specified time. The gradient of the tangent to the curve at that point represents the instantaneous radial velocity. The second derivative at that point, if it exists, would represent the acceleration.
A control limit on the graph for a process represents a point where the operator needs to take some predefined action.
The slope of the curve at each point on thegraph is the speed at that point in time. (Not velocity.)
