Answer:

The graphs intersect one time

Explanation:

we have


y=2x+4 ----> equation A


y=-x+4 ----> equation B

we know that

The solution of the system of equations is the intersection point both graphs

using a graphing tool

The graphs intersect only at one point

so

The system has only one solution

The intersection point is (0,4)

therefore

The solution is x=0, y=4
