Question

Find the intersection of the two lines by solving the system of equations.

x + y = -8
-x + y = -2

Answer 1

(-3, -5)

Explanation:

Adding the equations, we get 2y = -10, and thus y = -5.

Substituting this back into the first equation gives us that x = -3.

So, the point of intersection is (-3, -5).
