i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.
i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).
in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.
then the standard form of the equation is finding an expression of y in function of x
hope that .
do you confirm there was a mistake in the question?
answer: it's d
the answer to this question is d: 35
5 to the power of 2 is 25
2 multiplied by 5 is 10
then you add the 2 numbers and you get 35
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.
