Fill in the coordinates accordingly:

which simplifies down to

which is of course

Plug that into your calculator and you'll get the answer
That would be 5, all you need to do is divide by 2 or mltiply by 0.5 to get half of a number
A. 4*1 - 3*2 = 4 - 6 = -2 (X
B. 4*4 - 3*2 = 16 - 6 = 10 (O
C. 4*7 - 3*6 = 28 - 18 = 10 (O
D. 4*4 - 3*(-3) = 16 + 9 = 25 (X
so the answers are B and C
Answer: 23 + 9 = 32
