Answer:
-6/7
Step-by-step explanation:
The slope of the line perpendicular to DE is the negative reciprocal of the slope of DE. The slope of DE is ...
(change in y)/(change in x) = (y2 -y1)/(x2 -x1) = (-3-4)/(1-7) = -7/-6 = 7/6
The inverse of that is 6/7, and the opposite of that inverse is -6/7.
The slope of the line perpendicular to DE is -6/7.
according to the picture we have:
x.y=4.7
(7)x(7)y=49xy=(49)(4.7)=230.3
0.052 acre/min
6 1/4 acres / 2 hours times the conversion factor (1 hr / 60 min) comes out to:
6.25
----------------- = 0.052 acre/min
2 (60 min)
---------
-8/3
find slope
(-1,5) ( 2,-3 )
(-3 -5)/( 2-(-1)) = -8/3
Factor out the common term :
