Answer:
1. y = - 4 x + 5
2. x = -8
Step-by-step explanation:
1. (-1,9) (1,1)
y = mx + b
m = (y-y') / (x-x') = (1-9) / (1-(-1)) = -8 / 2 = - 4
b = y - mx = 9 - (-4) x (-1) = 5
equation: y = - 4 x + 5
check: (1,1) y=1 = (-4) x 1 + 5 = 1
2. Vertical line through (-8,6) is a line perpendicular to x axis
x = -8
The lot is <u>9.2% of the an acre.</u>
<u>Given:</u>
Area of an acre = 4840 sq. yards
Area of lot = 40 by 100 ft =
Convert the area of the lot to feet ():
<em>Therefore:</em>
Area of lot =
Percentage occupied by the lot = area of lot / area of acre x 100
The lot therefore is <u>9.2% of the an acre</u>.
