The cost of fencing (C)
The cost is calculated as:

Let:

So, we have:



<em>The question cannot be solved further since the dimension of the fence is not given</em>
<em>If you know the dimension, calculate the fence perimeter and substitute the value for x</em>

Answer:
y = -x+3
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 2 - -3)/( 1 - 6)
( 2+3)/( 1-6)
5/ -5
-1
The slope is -1
We can use slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -x+b
Substitute a point into the equation
2 = -1 +b
Add 1 to each side
2+1 = -1+1+b
3 = b
y = -x+3
