Is y = 10/x linear and why

Yes this is linear due to the fact that they are combining the letters x and y because they are a linear pit

The answer is B

Since the product is negative we exclude A because positive*positive doesn't yield negative.

B. -2 + 14 = 12 AND -2*12 = -28 (Which is the correct answer)

C. -14 + 2 = -12 AND -14*2 = -28 (But it is the wrong answer because it yielded negative 12)
