Answer: 2: an equation in the form y = mx + b
1. An x/y table may have two entries with the same x; not a function in that case.
2. That's a line with a slope; for each x there's a single y, definitely a function
3. Ordered pairs -- like the table, the same x with different ys is possible, which wouldn't be a function.
4. List of numbers -- a list isn't a function, at least not without more context
Answer: It think that 3 is adjacent to 5
49.10 - 5
44.10
44.10/2.10
21
So, the equation would be:
(49.10 - 5)/2 = 21
Hope this helps!
