Answer:
1/2 is the pre image for this
Given inequality is:

Now for (6,-4), Put x=6 nd y=-4 in given inequality:

So for (6,-4) this inequality is true.
For (-2,-3) put x=-2 and y=-3 in given inequality:

As -32 is less than -8 then this condition is also true.
simillarly you can check for other options also.
For (-7,5) Put x=-7 and y=5 in given inequality:

As 12 is grater than -8 so this condition is false.
And for (-6,0) put x=-6 and y=0 in given inequality:

As -24 is less than -8 so it is true.
(I)
we are given when we add numbers of same sign
For exp: +2+3=+5
-2-3=-5
We can see that we are adding numbers and then we put same sign in front
so, we can fill spaces
When adding integers with the same sign, you add the numbers and put the sign
(II)
we are given when we add numbers of different signs
For exp: 2-3=-1
-2+3=+1
We can see that we are subtracting numbers and then we put sign of largest value in front
so, we can fill spaces
When adding integers with different signs you subtract the numbers and use the sign of the largest absolute value
Angle: 180-132 = 48
180-48= 132
132/6=22
2(22)= 44
4(22)= 88
44+88+32 = 180
Answer:
Measure of angle < CBA = 88
Measure of angle < BCA = 44
