Question

what does the solution of (-2,-5) for the system of equations 9x-8y=22 and -10x + 5y= -5 indicate on the coordinate plane?

Answer 1

see the explanation

Explanation:

we have

`9x-8y=22` ----> equation A

`-10x+5y=-5` ---> equation B

we know that

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

The solution of the system is the point (-2,-5)

therefore

The point (-2,-5) indicate on the coordinate plane the intersection point both lines ( a common point for both lines)
