Question

Which matrix equation represents this linear system?

`2x-7y=-1\\x+3y=-5`

Answer 1

B

`2x - 7y = - 1 \\ \\ \\ 1. \: 2x = - 1 + 7y \\ 2. \: 2x = 7y - 1 \\ 3. \: x = (7y - 1)/(2)`

Answer 2

The answer is the letter B.

The first column represents the x-values, and the second row represents the y-values.

For that reason, if we have:

2x - 7y = -1

x + 3y = -5

Then, the matrix will be given by:

[ 2 -7

1 3]

Then, the third colum will be the equality:

[ -1

-5]

So the correct option is the letter B.
