The slope within two sets of points is calculated using the slope equation
The slope of a line or points is the rate of change of the line.
This in other words means that, the vertical change per unit horizontal change
Assume that the points are given as:
(x1, y1) and (x2, y2)
The slope (m) of the points is:
Hence, the equation of two sets of points is

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)
