The table shows three values of $x$ and their corresponding values of $y$. There is a linear relationship between $x$ and $y$. Which of the following equations represents this relationship?
Answer:
C
Explanation
The correct answer is Choice C.
The tabulated data must be analyzed to determine the linear relationship.
Choices A and B are incorrect because the slope is positive when $y$ clearly decreases as $x$ increases.
Choice D is incorrect because the $y$-intercept is wrong.
