Answer: I think that it is the first one
Answer:
x=-5, y=-2. (-5, -2).
Step-by-step explanation:
x-3y=1
-x+6y=-7
----------------
3y=-6
y=-6/3
y=-2
x-3(-2)=1
x+6=1
x=1-6
x=-5
Let's plug the coordinate point values into the equation:

(1,3) is
x₁ and (3,1) is x₂
Begin to simplify within the parenthesis:

Square the two numbers:
Add the two to get:
Since 8 is not a square number, this is as far as we can simplify this. Hope this helps!
