#"speed" = (Delta d)/(Delta t)#

Explanation:

An algebraic graph shows #x# values on the horizontal axis and #y# values on the vertical axis. The slope of a line indicates how steep it is.

A steep line means that the #y# values change more than the #x# values, while a gentle gradient means that the change in the #x# values is greater than in the #y# values.

#m = (Deltay)/(Deltax)#

In Physics, if an object is moving, we can draw a graph of its journey, plotting how far an object has moved (distance), in a a certain time.

Distance is shown on the vertical (#y#) axis and time is shown on the horizontal (#x#) axis.

The slope of such a graph is an indication of the SPEED.

A steeper line shows that a further distance was covered in a short time, so this indicates a FAST speed. Whereas, a line with a gentle slope means that the object was travelling SLOWLY because a short distance is covered in a longer time.

#"speed" = (Delta d)/(Delta t)#
