Acres = 640 * sq miles
acres = 640 * 3.5
acres = 2,240 square miles

**************************************************************
Incidentally, here's how that 640 acres per square mile is derived.
1 acre = 43,560 square feet
1 square mile = 5,280^2 = <span> <span> <span> 27,878,400 </span> </span> </span> square feet
<span> <span> 27,878,400 </span> / 43,560 = 640 acres exactly</span>

maksim [4K]

Answer:

y=-3/7x+2

Step-by-step explanation:

first formula (Slope): y2-y1/x2-x1

-1-2/7-0= -3/7

second formula (point slope): y-y1=m(x-x1)

y-2=-3/7(x-0)

(distribute the -3/7)

y-2=-3/7x-0

(add 2 to both sides)

y=-3/7x+2
