Answer:
y + 5 = 2(x−4)
Step-by-step explanation:
slope = 2
y = mx + b
-5 = 2(4) + b
-5 = 8 + b
-8 -8
------------------
-13 = b
y = 2x - 13, in other words --> y + 5 = 2(x−4)
So, y + 5 = 2(x − 4) is the equation of the line that passes through (4, -5).
-0.4x=2.5 divide both sides by -0.4
x=-6.25
In order to determine the area of the lot of land in squared yards, proceed as follow:
Convert the dimensions of the rectangle to yards, by using the given conversion factor:

Next, consider that the area of the lot is the area of a rectangle. Replace the previous values of the length and the width of the rectangle:

Hence, the area of the lot of land is 656.25 sq yd
The formula to use is:
A=P(1+r/n)^nt
Plug in the values:
A=1400(1+.06/2)^2(10)
A=$2528.56 (rounded off)
