Answer:
A) ![-3x+y=-7](https://tex.z-dn.net/?f=-3x%2By%3D-7)
Step-by-step explanation:
Slope of the line:
![\frac{5-(-1)}{4-2} =\frac{6}{2} =3](https://tex.z-dn.net/?f=%5Cfrac%7B5-%28-1%29%7D%7B4-2%7D%20%3D%5Cfrac%7B6%7D%7B2%7D%20%3D3)
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
![y=3x+b](https://tex.z-dn.net/?f=y%3D3x%2Bb)
Plug in x and y values of any of the points.
![5=3(4)+b](https://tex.z-dn.net/?f=5%3D3%284%29%2Bb)
![5=12+b](https://tex.z-dn.net/?f=5%3D12%2Bb)
![b=-7](https://tex.z-dn.net/?f=b%3D-7)
Equation of the line:
![y=3x-7](https://tex.z-dn.net/?f=y%3D3x-7)
Subtract 3x from both sides:
![y-3x=-7](https://tex.z-dn.net/?f=y-3x%3D-7)
![-3x+y=-7](https://tex.z-dn.net/?f=-3x%2By%3D-7)
A is correct.
Zero does not have a opposite, because it is not a positive number nor a negative number. It has no reciprocal either

Although there are several ways of solving this problem, I just did what was easiest for me in my head. I divided 36 by 4, which gave me 9.
The area of the L shaped figure is 258 ft²
<h3>
Area</h3>
Area is the amount of space occupied by a two dimensional figure.
The area of a rectangle is given by:
Area = length * breadth
From the diagram, the area is:
Area = [18 * (21 - 12)] + (12 * 8) = 258 ft²
The area of the L shaped figure is 258 ft²
