Answer:
Option C is the answer.
Step-by-step explanation:
To find the equation of the straight line equation i.e, we must be given with the two points
and ![\left (x_{2},y_{2}\right )](https://tex.z-dn.net/?f=%5Cleft%20%28x_%7B2%7D%2Cy_%7B2%7D%5Cright%20%29)
Since from the graph the two points closest to the line are
and ![\left ( 22,12 \right ).](https://tex.z-dn.net/?f=%5Cleft%20%28%2022%2C12%20%5Cright%20%29.)
Equation of line with two points closest to the line :
![y-y_{1}=m\cdot \left ( x-x_{1} \right )](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%5Ccdot%20%5Cleft%20%28%20x-x_%7B1%7D%20%5Cright%20%29)
where m is the slope.
First we find the slope(m)=
![m=\frac{12-36}{22-10}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B12-36%7D%7B22-10%7D)
on simplify we get,
.
Now, to find the equation of the line: ![y-y_{1}=m\cdot \left ( x-x_{1} \right )](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%5Ccdot%20%5Cleft%20%28%20x-x_%7B1%7D%20%5Cright%20%29)
![y-36=\left ( -2 \right )\cdot \left ( x-10 \right )](https://tex.z-dn.net/?f=y-36%3D%5Cleft%20%28%20-2%20%5Cright%20%29%5Ccdot%20%5Cleft%20%28%20x-10%20%5Cright%20%29)
Apply distributive property on right hand side, we get
Adding both sides by 36, we get
![y=-2x+20+36](https://tex.z-dn.net/?f=y%3D-2x%2B20%2B36)
.
The equation for the linear model in the scatter plot obtained by the two closest point
closest to the line is,
![y=-2x+56](https://tex.z-dn.net/?f=y%3D-2x%2B56)

im not sure but i think it is -7
Step-by-step explanation:
i think so just because looking at the top example but i might be wrong
Answer:
x = 50, y = 10
Step-by-step explanation:
![\\(5x-100)+(x-20) = 180 => 6x = 300 => x = 50\\(3y)+(y+140) = 180 => 4y = 40 => y = 10](https://tex.z-dn.net/?f=%5C%5C%285x-100%29%2B%28x-20%29%20%3D%20180%20%3D%3E%206x%20%3D%20300%20%3D%3E%20x%20%3D%2050%5C%5C%283y%29%2B%28y%2B140%29%20%3D%20180%20%3D%3E%204y%20%3D%2040%20%3D%3E%20y%20%3D%2010)
