Answer:
to compare she must calculate...
1) ((2*3)+2)/3 she get 2.666
2) ((2*7)+5)/7 she get 2.714
by approximation the two are the same and she had enough flour.
Given:
The table of values is
x y
-4 2
-3 5
-2 8
-1 11
To find:
The slope of the line that contains these points.
Solution:
From the given table consider any two point.
Let the line passes through the points (-4,2) and (-3,5). So, the equation of the line is
![y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%28x-x_1%29)
![y-2=\dfrac{5-2}{-3-(-4)}(x-(-4))](https://tex.z-dn.net/?f=y-2%3D%5Cdfrac%7B5-2%7D%7B-3-%28-4%29%7D%28x-%28-4%29%29)
![y-2=\dfrac{3}{-3+4}(x+4)](https://tex.z-dn.net/?f=y-2%3D%5Cdfrac%7B3%7D%7B-3%2B4%7D%28x%2B4%29)
![y-2=\dfrac{3}{1}(x+4)](https://tex.z-dn.net/?f=y-2%3D%5Cdfrac%7B3%7D%7B1%7D%28x%2B4%29)
Using distributive property, we get
![y-2=3x+12](https://tex.z-dn.net/?f=y-2%3D3x%2B12)
![y=3x+12+2](https://tex.z-dn.net/?f=y%3D3x%2B12%2B2)
![y=3x+14](https://tex.z-dn.net/?f=y%3D3x%2B14)
Therefore, the required equation of line is
.
