2. Construct Arguments Macy says that any time the equations in a system have the same

y-intercept, the system has infinitely many

solutions. Is Macy correct? Explain.

Answer:Incorrect.

For example, two equations with same y intercept.

y = 2x + 3

y = 5x + 3

This system has only one solution.

Another example,

y = x + 7

y = x + 7

This system has infinitely many solutions.

So she is not correct because of the first example.
