Answer: d
Explanation:
To solve this question, you have two methods.
One is graphing the inequalities and finding the points that match them, and the other is plugging the values of the points into the inequalities and checking to see if it is true or false.
I chose the latter method for convenience's sake.
The inequalities show that
y<-2x+10
y<1/2x-2
Since this is a multiple-choice question, we only need to plug in the values of the choices. For a student's response question, you'll need to plug in all the points if you use this method.
Let's plug in I.
I is located at (9,3).
So if you plug in the values,
3<-2*9+10 is false.
So a is false.
Next, B.
B is located at (4,7).
7<-8+10 is false.
So b is false.
Next, A.
A is located at (-5,4)
4<10+10 is true.
4<1.2*(-5)-2 is false.
So the answer is d.
