Answer:
A(2/3, 6)
B(15, 33)
Slope=81/43
Step-by-step explanation:
If for the first point A Y=6, you can just plug it into the spot for the Y in the equation.
So that get's you the equation 6-2x=3
Solving the equation you get:
2x=3
x=2/3
So that means that for point A your coordinate pair is (2/3, 6)
You do the same for B.
B has point X=15, so plug it in:
y-2(15)=3
y-30=3
y=33
So your coordinate pair for B is (15, 33)
Then to find the slope you follow the equation y2-y1/x2-x1
Plugging in the numbers you get:
33-6/15-2/3
27/43/3
81/43
So your slope=81/43
Let
x---------> the length side of rectangle
y---------> the width side of rectangle
we know that
x=2y-----> equation 1
area=x*y-------> 28800=x*y------> equation 2
substitute 1 in 2
28800=[2y]*y-----> 28800=2y²-------> y²=14400------> y=120 m
x=2*y----> x=2*120------> x=240 m
the answer is
the length side of rectangle is 240 m
the width side of rectangle is 120 m
