Best ResponseYou've already chosen the best response.1In an ordered pair the first number is x and the second is y. So, if I have an ordered pair of (2,6). x is 2 and y is 6. Now look at your choices. the only relation that an x doesn't repeat is choice B, because your x's are: 1,2,4,9.

Best ResponseYou've already chosen the best response.1vertical line test also proves what I'm saying. If you plot the points and draw vertical lines through each point. Then each line should only go through one point. More than one point makes it NOT a function and if you graph D a vertical line would go through x at 6 twice which proves D is WRONG!
