Answer 1

To find the slope, we use the formula for slope,

$m=\frac{y_{2}-y_{2}} {x_{2}-x_{1}}$

Letting the point (2,5) be $(x_{1},y_{1})$ and the point (4,10) be $(x_{2},y_{2})$.

Now plugging in these values in the formula for slope, we get,

$m=\frac{10-5}{4-2} =\frac{5}{2}$. The slope is $\frac{5}{2}$.

This basically means 5 mm of rain falls in every 2 hours, or 2.5 mm of rain falls every hour ($\frac{5}{2} =2.5$)

ANSWER: Slope is $\frac{5}{2}$ and 5 mm of rain falls every 2 hours.

Answer 2

The slope is 5/2. count up 5 then go right 2. this means that 5 mm of rain falls every 2 hrs
