Answer:
![y=-11x+261](https://tex.z-dn.net/?f=y%3D-11x%2B261)
Step-by-step explanation:
As you can observe in the image attached, the line that best fits passes through point B and C. That means we can use those point to find the slope of such line.
![m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D%20-y_%7B1%7D%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
Where
and ![C(12,126)](https://tex.z-dn.net/?f=C%2812%2C126%29)
![m=\frac{126-137}{12-11}=-11](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B126-137%7D%7B12-11%7D%3D-11)
So, the slope of the line that best fits is -11, approximately.
Now, we use the point-slope formula to find the equation.
![y-y_{1} =m(x-x_{1} )\\y-137=-11(x-11)\\y=-11x+124+137\\y=-11x +261](https://tex.z-dn.net/?f=y-y_%7B1%7D%20%3Dm%28x-x_%7B1%7D%20%29%5C%5Cy-137%3D-11%28x-11%29%5C%5Cy%3D-11x%2B124%2B137%5C%5Cy%3D-11x%20%2B261)
Therefore, the line that best fits is
approximately.
Remember, when we estimate a line for some data on a scatterplot, we are calculating an approximation, that's why we also said "approximately", because the line is an approximation where the majority of point meet.
Answer:
The jacket costs $45
Step-by-step explanation:
In order to find this, notice that the price of the sale represents 80% of the total cost. This is because we took 20% away with the sale. Now we can find the overall amount by dividing the sale cost by the amount it represents.
$36 / 80% = $45
Google it.... <em> </em>I just did and there is a video.
Multiply the amount she deposits every month by the number of months (m) and add it to her starting amount:
The equation will look like this:
y = 30m + 16
