Hello there!
Y = -x - 2
Y = 3x + 2
We need to substitute -x -2 for y in y = 3x + 2
-x - 2 = 3x + 2
-x = 3x + 2 + 2
-x = 3x + 4
-x - 3x = 4
-4x = 4
x = 4/-4
x = -1
Then substitute -1 for x in y = -x -2
y = -x -2
y = -(-1)-2
y = 1 - 2
y = -1
The answer is y = -1 and x =-1
So in the box, you should put (-1, -1)
I hope this helps!
