Question

A system of linear equations has been graft in the diagram determine a reasonable solution for a system of equations,A. (2,1)B. (-2,1)C. (2,-1)D. (3,-1)

Answer 1

The solution of the system of the linear equation is the point where the linear graphs (lines) intersect.

by observation, the point of intersection is to the right of the origin zero on the x-axis and above the line y=0 ( x-axis line).

This implies that the x and y values of the coordinate are positive for both

Hence, the solution for the system of the linear equations is

`(2,1)`

Option A is the answer
