graph the system of equations below on a piece of paper what is the solution
y=x-1
y=3x+1
a) (1,-2)
b) (-1,-2)
c) (2,1)
d) (-1,-1)

B)

Step-by-step explanation:

3x + 1 = x - 1

-3x - 3x

___________

1 = −2x - 1

+1 + 1

_________

2 = −2x

_ ___

−2 −2

[Plug this back into both equations above to get the y-coordinate of -2];

I am joyous to assist you anytime.
