The equation of a line that passes through (x1,y1) and has a slope of m is
y-y1=m(x-x1)


find slope

slope between (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(-3,2) and (2,1)
slope=(1-2)/(2-(-3))=(-1)/(2+5)=-1/5


pikc a point
if we pick (-3,2)
(x1,y1)
x1=-3
y1=2

y-2=-1/5(x-(-3))
y-2=-1/5(x+3)
that is D

Zielflug [23.3K]
Area = length x width = (0.8 x 5280) x (1.1 x 5280) = 4224 x 5808 = 24532992 square feet.

43,560 square feet = 1 acre
24,532,992 square feet = 24,532,992/43,560 = 563.2 acre
