Required
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:
1. (AB) y = 2/3x + -4
Step-by-step explanation:
Formula - y = m(x) + (y-intercept)
m = rise / run
"run = horizontal (left and right)
rise = vertical (up and down)"
the y intercept is always going to be where y is 0 at. (x, y) you will use your x to determine the intercept
So lets use your first question as an example
1. (AB) y = m(x) + (y-int)
y = m(x) + (-4)
the point goes to the right 6 points and goes up 4 points (rise / run)
y = 4/6(x) + (-4)
You can round up the fraction to 2/3
y = 2/3(x) + -4
Here, Equation would be: 3.2x = 48
Where, x = 1 cm for certain distance in real
x = 48/3.2
x= 15
In short, Your Answer would be 15 Feet
