Answer:
The closest approximate solution to the system of equations is the point [tex](-5,-6.8)[/tex]
Step-by-step explanation:
we know that
The solution of the system of equations is the intersection point both graphs
In this problem
The x-coordinate of the intersection point is [tex]-5[/tex]
The y-coordinate of the intersection point belong to the interval---> [tex](-6.5,-7)[/tex]
therefore
The closest approximate solution to the system of equations is the point [tex](-5,-6.8)[/tex]
Verify
[tex]7x-4y=-8[/tex] ------> equation A
[tex]y=(3/4)x-3[/tex] -------> equation B
using a graphing tool
see the attached figure
The exact solution is the point [tex](-5,-6.75)[/tex]
