PLEASE HELP ME (40 POINTS)

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)

Answer 1

For each equation give X a value and solve for Y, do this at least two times for each equation.

Plot those dots on a graph to draw two lines.

The solution is where the two lines cross.

You will see the lines cross at (-1,-2)
