Answer:
100
Step-by-step explanation:
Multiply 50 by 2
Simple...
you have: (7,-7) and (6,-5)
Using

to find slope--->>>

=-2
m=-2
Using y=mx+b to find the equation of the line-->>(Use any of the coordinates)
(7,-7)
-7=-2(7)+b
-7=-14+b
-7=-14+b
+14 +14
7=b
y=-2x+7Thus, your answer.
Sense its 10 feet apart and there is 130 feet of stright line fence it will be 13 posts
