Given a set of values
{(2,7). (8, 12). (5,9). (10.15)),
determine which numbers do not
belong in the following examples.
Why?
Explain in your own words.
Domain: (2,5, 7, 8, 10)
Range: (7.9. 10. 12. 15)

Answers

Try to determine the value when they all add up. Or If you’re working with fractions try cross canceling

Step-by-step explanation:

given : (2,7). (8, 12). (5,9). (10.15)

domain: will always be the first value of numbers ; 2, 8, 5, 10

range: will always be the second value of numbers ; 7, 12, 9, 15

what you have here is :

Domain: (2,5, 7, 8, 10)  

Range: (7.9. 10. 12. 15)

what's wrong is 7 is in the domain, and 10 is in the range. those two don't belong there.  theres also a extra number you have in there. domain and range should only have 4 numbers.  since there is four pairs/set of values

Answers

Answer: A) y = 7x - 22

Explanation: First of all, we know it cannot be D, because if the answer was D, the slope would have to be 14. Next, to find the value of b (the y intercept) we have to do 7(3) and we will then get 21. We then must subtract 21 from -1 and get the slope of -22. The reason we subtract is because we must make the x value 0, and since it is 3, we go backwards. Hope this helped!
