Distance versus time graphA distance versus time line graph shows the speed of an object.
On this type of graph, time must be on the x-axis and distance must be on the y-axis.
When making this type of graph be sure to label each axis with a proper unit.

SlopeSlope is the steepness of the line
The steeper the line, the greater the speed.
The graph shows that Car 3 has a greater speed than Car 1 and Car 2.

Reading a distance versus time graph A straight line on a distance versus time graph shows constant speed (cruise control) Car 1
A horizontal line shows that the object is not moving. Car 2 is parked.

Interpreting the graph Most objects don’t go a constant speed. So most distance versus time graphs are not straight lines.

Think of a trip to the mall.
First, you go slow down your street.
Then you go faster down the main street.
You may stop because of a red light.
You drive some more and then you arrive at the mall.
Finally, you park.

Review: Draw the graph below Distance must be on the y-axis and time must be on the x-axis. Include the proper units.
A straight line shows a constant speed. Car 1
The steeper the line, the greater the speed. Car 2
A horizontal line shows the object is not moving. Car 3
Car 1
Car 2
Car 3
Car 4
What is happening to Car 4?
