Answer:
- 
Step-by-step explanation:
Given the 2 by 2 matrix
![\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%5C%5Cc%26d%5C%5C%5Cend%7Barray%7D%5Cright%5D)
The determinant = ad - bc
For the given matrix
a =
, b =
, c =
, d =
, thus
ad - bc =
×
- (
×
) =
-
= - 
The answer would be (4,3)
