This is a function because all the x values are different automatically making it a function. But if there were two of the same x values and they had different y values it wouldn’t be a function. Hope that makes sense!

If you apply the linear combination method to the system like:
<span>4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Then you can be sure that the solution of all this system is: (9,3). Hope this si what you were looking for</span>
