Question

This graph shows the amount of rain that falls in a given amount of time.

What is the slope of the line and what does it mean in this situation?

The slope of the line is ___

This means that ___ mm of rain falls every ___

Answer 1

Using the formula for finding slope...

y2 - y1 10 - 5 5
---------- = -------- = -----
x2 - x1 4 - 2 2

The slope of the line is 5/2.
This means that 5 mm of rain falls every 2 hours.
