I think it is −2.666666666666667 but i’m not sure!
The answer of this question is C. Because the different on y value is increasing by 2 so it’s linear
Answer: 54.33%
<u>Explanation:</u>
14 carat gold contains 58.33% gold and 4% silver (since we are using the lowest percentage).
58.33% - 4% = 54.33%
There is 54.33% more gold than silver in the 14 carat gold mixture.
The slope is 2.
The slope is 1/2.
