Question 1118925
<br>
I haven't seen matrices displayed this way; however, the question you asked makes it clear how the display is to be interpreted.<br>
The two rows of the first matrix contain the coefficients of the two variables in the two equations: [-1 2] and [0 1].
The two rows in the second matrix contain the two variables: [x] and [y].
The product matrix contains the constant terms of the two equations when they are in Ax+By=C form: [0] [-2]<br>
So answer B.
