Answer:
The coordinates of the intersection point are 
Step-by-step explanation:
we have
-----> equation A
-----> equation B
-----> equation C
we know that
If the system of equations intersect at one point, then the system of equations has one solution
using a graphing tool
see the attached figure
The coordinates of the intersection point are 
This point is a common solution for the three equations
Verify
Substitute the value of
in each equation
so
Equation A

----> is true, therefore the point is a solution of the equation A
Equation B


----> is true, therefore the point is a solution of the equation B
Equation C

----> is true, therefore the point is a solution of the equation C
The answer is A because when a number has a 0 above it’s always 1
