Question

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

The slope of the line is____This means that____millimeters of rain falls every____hours.

Answer 1

Slope is 5/2 and 5 mm of rain falls every 2 hours.

Answer 2

see explanation

Explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 5) and (x₂, y₂ ) = (4, 10) ← 2 points on the graph

m =
`(10-5)/(4-2)` =
`(5)/(2)`

This means that 5 mm of rain falls every 2 hours
