Question

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 1

she is incorrect

Explanation:

she is incorrect because even though the equation has the same slope but the x value can be diffrernt which can lead to a different answer

Answer 2

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.
