We are given two functions.


f(x)=x-4\\g(x)=-x-2

The point that represents the equation
f(x)=g(x), will also be the intersection of those two lines, meaning we can set the two equations equal to each other and solve for
x.


f(x)=g(x)\\x-4=-x-2\\2x=2\\x=1

Now that we are given the x value, we can plug this value back into either equation and solve for the y value.


f(1)=1-4\\f(1)=-3

The point of intersection will be
(1,-3).

Hope this helps!
