How Do I Plot an Acceleration-Time Graph from a Given Velocity-Time Graph?

[n3w ton]

Homework Statement

I need help plotting the acceleration time graph from a given velocity-time graph.

Homework Equations

I know you need to do slope [Which is already provided] [9.40 m/s²]

I also attached the distance-time graph [first one] and I also attached the velocity time graph [graph 2]

Did I do it right, please correct it thank you!

The slope of the position vs. time graph is velocity.

The slope of the velocity vs. time graph is acceleration.

Your acceleration looks reasonably constant at ‒9.4 m/s².
