Answer:
the answer is d; the slope is 4, and the y-intercept is 12
Step-by-step explanation:
the slope is actually 4/-1, but the y-intercept is still 12 thow.
so it went down from 25 to 18, so 25 - 18 = 7.
if we take 25 to be the 100%, what is 7 off of it in percentage?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 25&100\\ 7&x \end{array}\implies \cfrac{25}{7}=\cfrac{100}{x}\implies 25x=700 \\\\\\ x=\cfrac{700}{25}\implies x=28](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%2025%26100%5C%5C%207%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B25%7D%7B7%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%2025x%3D700%20%5C%5C%5C%5C%5C%5C%20x%3D%5Ccfrac%7B700%7D%7B25%7D%5Cimplies%20x%3D28)
