Digital SAT Math Test 4 Question 6

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.

✨ Expert's Tip ✨

An alternate method is to substitute coordinates into the given equations to verify them.
