Answer:
y=1/2x-6
Step-by-step explanation:
y-y1=m(x-x1)
y-(-1)=1/2(x-10)
y+1=1/2x-10/2
y=1/2x-5-1
y=1/2x-6
Answer:
The cost of fertilizing the field is 
Step-by-step explanation:
we know that
The area of the figure is equal to the area of the rectangle plus the area of a complete circle (two semicircles)
Step 1
Find the area of the rectangle
The area of rectangle is equal to

where
L is the length side of rectangle
w is the width side of the rectangle
In this problem we have


substitute

Step 2
Find the area of the circle
The area of the circle is equal to

where
r is the radius of the circle
In this problem we have

substitute

Step 3
Find the area of the figure
Adds the area of rectangle and the area of the circle

Step 4
Find the cost
Multiply the total area by 
so
