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
