How many times do the graphs of
the equations y = 2x + 4 and
y = -x + 4 intersect?

The graphs intersect one time

Step-by-step explanation:

we have

----> equation A

----> 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

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.
