Question

What type of system of linear equations is this?

y = –3x – 1
3x + y = – 1

Answer 1

here is your answer:-

linear equations in two variables

Answer 2

Y = - 3 x - 1

3 x + y = -1

---------------

3 x - 3 x - 1 = -1

0 · x = - 1 + 1

0 · x = 0

x, y ∈ R

There are infinitely many solutions.
