You first divide the number by 100 and then multiply it by the percentage that you are given
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.
0.0000009
.9 times 10 is 9, so then you have to move it back -6 times behind the decimal.
