Question

1.) Which system of equations below give the solution (-1,-2)?

(1)
(3)
y = x - 3
y = -x - 1
y = -x - 3
y = x - 1
(2)
y = x - 3
(4)
y = -x - 3
y=-x-1
y = x - 1

Answer 1

y = -x - 3

Explanation:

Plug in -1 for x and your result will come out to 1 because of that double negative [-(-1) = 1]. Next, deduct 3 from 1 to get -2.
