To find the slope of the line, we can use the formula:
Slope = (change in y)/(change in x)
We have two points (3,2) and (12,8). Let's calculate the change in x and change in y:
Change in x = 12 - 3 = 9
Change in y = 8 - 2 = 6
Now, we can find the slope:
Slope = 6/9 = 2/3
The unit rate of the slope is 2/3, which means for every 3 hours, there is an increase of 2 inches in rainfall.
