Now as the schools with percent free lunch are 8 so now
So only 2 schools will be selected in this regard.
Given:
The given point is (4,12).
To find:
The equation that would NOT contain the point (4,12).
Solution:
We need to check each equation for the point (4,12).
In option A, the given equation is:
Putting , we get
This equation contains the point (4,12).
In option B, the given equation is:
Putting , we get
This equation does not contain the point (4,12).
In option C, the given equation is:
Putting , we get
This equation contains the point (4,12).
In option D, the given equation is:
Putting , we get
This equation contains the point (4,12).
Only the equation in option B does NOT contain the point (4,12). Therefore, the correct option is B.
