Question #5cac3

Answer 1

`"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)`
