Answer:
Yes.
Step-by-step explanation:
If you write out the coordinates, you can see that you can do the Vertical Line Test and confirm that if you were to write a function, it would be an actual function. No 2 x-values can be the same y-values. The coordinates all have separate xy values (or the same exact xy values) and you can determine a function.
Answer:
YES
Step-by-step explanation:
let's organize our information :
- We notice that the values of the height of the table are changing as the height of the chais is changing
- 75⇒46
- 74⇒44
- 76⇒47
- 75⇒46
- 72⇒43
- 77⇒48
- 76⇒47
- 71⇒42
Notice how when the chair's height is growing by 1 the same happens for the tables
- so they are proprtional
- we can say tha x is the height of table is x and the height of the chais is y
- x=71 y=42 x=72 y=43
- when we added 1 to x the same happened for y x+1⇒y+1
- notice : 71-42=29 , 72-43=29 so x-y= 29
- then x=y+29
