Answer:
y=-x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-1)/(5-3)
m=-2/2
m=-1
y-y1=m(x-x1)
y-1=-1(x-3)
y-1=-x+3
y=-x+3+1
y=-x+4
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
