The slope of the line below is 2. which of the following is the point-slope form
of the line?
(1,-1)
a. y+1 = -2(x - 1)
b. y-1 = 2(x+1)
c. y-1 =-2(x+1)
d. y+ 1 = 2(x-1)

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
