parallel lines have negative reciprocal slopes
so 1/2 becomes -2
point slope form
y-y1 =m(x-x1)
y-0 = -2(x--4)
y =-2(x+4)
y=-2x-8
Add 2 to both sides then divide 9 from both sides :)
Answer:perimeter
Step-by-step explanation:20+20+4=44 and u multiply 3/5x times 2 it equals 6/10x+44
The answer is 7418.
Hope this helps
A= πr2
d=10m
2r=d
2r=10
r=5
A= π•5^2
A=3.14 •25
A=78.5 m^2
