The Meaning of the Slope on a PT Graph

On a PT Graph the slope represents the displacement / distance travelled over the time it took to travel.

EX: the velocity (m/s)

EX: If a car is moving rightward and this data is shown, what would be the velocity of the car?

displacement (m)	time (s)
0	0
+10	1
+20	2
+30	3
+40	4

**It has a constant speed, positive / rightward / east / north.**

Formula for Slope:

Rise / Run OR change in Y / change in X

To determine the slope of a line, you must pick two points!

If an object is not moving, it is said to be "at rest".
