Consider the following equations - x - y = 1
y = x + 3

If the two equations are graphed at what point do the lines representing the two equations intersect?

1) (-1, 2)
2) (-2, 1)
3) (1, -2)
4) (2, -1)

​

2) (-2,1)

Step-by-step explanation:

Solve using the substitution method -x-(x+3)=1 using this equation you would find x which is -2

Substitute -2 into the given equation, y=-2+3   y=1

Therefore, The answer is (-2,1)
