Hello:
equation is the line is : y = ax+b a is a slope
y = (3/5)x+b
passing through the point (9;−4) : -4 =(3/5)(9)+b
b = - 4 -27/5 = -47/5
y = (3/5)x- 47/5
The answer is 12.2
I calculated it on the calculator
Start with the sum of x and 9, giving the expression
![x + 9](https://tex.z-dn.net/?f=x%20%2B%209)
This is divided by 2 so
![\frac{x + 9}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%20%2B%209%7D%7B2%7D%20)
This equals 3x so the equation is
![\frac{x + 9}{2} = 3x](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%20%2B%209%7D%7B2%7D%20%20%3D%203x)
This can the be solved.
Multiply both sides by 2 to get
![x + 9 = 6x](https://tex.z-dn.net/?f=x%20%2B%209%20%3D%206x)
Then take x from both sides
![9 = 5x](https://tex.z-dn.net/?f=9%20%3D%205x)
Divide by 5 to get the value for x
The area of a square can be calculated by the square of its side length. It is expressed as:
Area = s^2
s = square root of the area
s = √68
s = 2√17 ft
