Provide an appropriate response.Given the following system of equations:-5x + 20y = -2520x + 20y = -25,is it possible to change exactly one coefficient or constant to make the system dependent? Make the change if it is possible. Explain your answer.
What will be an ideal response?
Yes, it is possible. Change the x-coefficient in the first equation to 20. The two equations will then be equivalent, and their graphs will be the same line.
