Answer:

Velocity

Step-by-step explanation:

x-t curve means position vs time graph in which position (x) is in x-axis and time is in y-axis.

Slope of a graph =
$(\Delta y)/(\Delta t)$ .

We know that, velocity = displacement/time

or we can say that slope = displacement/time = velocity

Hence, the correct option is (b) "velocity".
