Question

Which matrix represents the system of equations shown below?
3x-2y = 4
6x- y = 10

Answer 1

B.

Explanation:

First equation: the coefficients of x and y are 3 and -2, and the constant is 4.

So the first row should be [3 -2 4].

Second equation: the coefficients of x and y are 6 and -1, and the constant is 10. Hence, the second row should be [6 -1 10].
