For the graph of y = -8 the line is horizontal, which means the slope = 0. A parallel line has the same slope so one equation could be y = 2. A perpendicular line has an opposite slope so since our slope = 0 the opposite of that slope is

which a line that is perpendicular to y = -8 could be x = -3. Also notice that these two lines form a 90 degree angle.
Answer:
Area of walkway = 16(x+4) 
Step-by-step explanation:
Length of the sides of the square outdoor = x feet
Area of the square outdoor = length x length
= x * x
=

The square outdoor is surrounded by 4 feet of walkway. So that,
length of the walkway = (x + 2(4))
= (x + 8)
Area of walkway with outdoor = (x + 8)*(x + 8)
= (
+ 16x + 64) 
Area of walkway = Area of walkway with outdoor - Area of the square outdoor
= (
+ 16x + 64) - 
= 16x + 64
Area of walkway = 16(x+4) 
I would say it's arc providing the curve possesses a constant rate of curvature.
And the curve by definition follows the rule.
Answer:
With 1 gallon of blueberries, Sam can fill 4/3 of his container.
Step-by-step explanation:
By the given situation:
1/2 gallon of blueberries ⇒ The container is 2/3 full
Now, let us assume 1 gallon of blue berries ⇒ The container is m full.
Now, by the RATIO OF PROPORTIONALITY:

Hence, with 1 gallon of blueberries, Sam can fill 4/3 of his container.
