Provide an appropriate response.Explain in your own words what it means for a system of two equations in two variables to be dependent.
What will be an ideal response?
The equations are equivalent. Thus, the graph of the system is a single line, and every point on the line is a solution of the system.This means that the system has an infinite number of solutions.
