The function of 5 (or y when x is 5) can not be determined with this little information.
Answer:
h=0
Step-by-step explanation:
h=0
28.95 is 14.7 greater than 14.25
Answer:

Step-by-step explanation:
Vertical lines take the form of
and horizontal lines take the form of 
Why is this? Notice that whenever you make a horizontal line on a graph and select virtually any point that's on that line, all of the points you pick will have the same y value. Try to imagine the same thing with a vertical line, are the results the same?
So the line
(we got -12 from the coordinate that was given to us on the question prompt) is a vertical line that passes through virtually all possible y values (from positive infinity to negative infinity, or vice-versa) which means that the question prompt having given us the y value was negligible.
Good luck!
Answer:
Undefined
Step-by-step explanation:
This is horizontal line, so the slope is undefined.
