SERIOUSLY DOES REAL PPL USE THIS APP PLS ANSWER Which coordinates have to be different and which could be the same in
a list of ordered pairs that is a function?

the x-coordinates have to be different, and the y-coordinates can be the same. if there were two points on a graph that had the same x-coordinate, the two points would be on top of each other at different y-values, preventing the graph from passing the vertical line test. if a graph passes the vertical line test, it is a function.

The answer would be

1. (582.85 - 64)/p Or D

And

2. 64.85 Or A
