Well, we know that Jody and Aaron both graphed a function, and an ordered pair will not disprove that.
Knowing that the notation for ordered pairs is (x,y) we can plug the ordered pair into each equation. Does that make since?

Not really, Can you break it down for me please?

anonymous · Answer

Alright, since any point on a plane is expressed in (x,y), and the ordered pair given is (1,-1), then then x = 1 and y = -1 at that point. In order for the ordered pair to satisfy the equation, the equation must be true when you plug in x and y. For example, if we were to plug the x and y values into x = y^2, what is on the left side must be equal to what is on the right side in order for the equation to be "satisfied." Plugging in the numbers, we would get 1 = (-1)^2. 
If (-1)^2 = 1, then the equation is satisfied. Does that make sense?

ohhhhhh ok ok thank youu

so then the answer is c?

anonymous · Answer

Are C and D supposed to say the same thing? You may have had a typo

anonymous · Answer

D is a typo that's suppose to say They satisfies neither equations
