Answer: option is A: An increasingly steeper slope
Explanation: Suppose that you are graphing the position of an object with increasing velocity.
in an x vs t graph.
as the velocity increases, the lapse of time needed to travel a fixed distance dx is shorter and shorter, so you will see a positive slope that as the time passes it will become more vertical (never being actually vertical)
Then the correct option is A: An increasingly steeper slope
