Jack and jill's place is a nonprofit nursery school run by the parents of the enrolled children. since the school is out of town, it has a well rather than a city water supply. lately, the well has become unreliable, and the school has had to bring in bottled drinking water. the school's governing board is considering drilling a new well (at the top of the hill, naturally). the board estimates that a new well would cost $3,150 and save the school $630 annually for 10 years. the school's hurdle rate is 8 percent.

step-by-step explanation:

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

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
