Dimensions of walkway and pool= (23+3) x (32+3) => 26ft x 35 ft
Perimeter: 2(l+w)
= 2 (26ft + 35ft)
= 122 ft fence would be required to enclose the walkway and the pool.
A standard line equation takes the form of y=mx+b
m= the slope so we see that 2 is next to x in your example
A) Slope = 2
Perpendicular lines will have the negative reciprocal of the original equation's slope
2 -> -
B)
