Completing the statements: The slope of the line is 5/2. This means that 5/2 mm of rain falls every 1 hour.
How to interpret slope?
The slope of a line represents the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line. The slope of the line above is calculated as: m = (5 - 10) / (2 - 4)
m = -5/-2
m = 5/ 2.
Since the slope of the line is calculated as 5/2, it represents the rate of change of the amount of rain over time. In this context, it means that 2.5 mm of rain falls every 1 hour. In order words, 5/2 mm of rain falls every 1 hour.
