Use a graphing tool to solve the system. {3x−8y=293x+y=−2 Which ordered pair is the best estimate for the solution to the system?

Hello, please refer to the attached file for the graph generated by Desmos.

The red line shows the graph for [tex]3x-8y=29[/tex] while the blue line is the graph for [tex]3x+y=-2[/tex].

Since Desmos automatically shows the intersection of two graphs, we know it's exactly the point with coordinates (0.481,-3.444).

Answer:

The best estimate for the solution is the point [tex](0.5,-3.5)[/tex]

Step-by-step explanation:

we have

[tex]3x-8y=29[/tex] -----> equation A

[tex]3x+y=-2[/tex] -----> equation B

we know that

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

Using a graphing tool

The intersection point is [tex](0.481,-3.444)[/tex]

see the attached figure

therefore

The solution of the system of equations is the point [tex](0.481,-3.444)[/tex]

The best estimate for the solution is the point [tex](0.5,-3.5)[/tex]
