Answer

$\boxed{\text{Therefore, the correct answer is (D) Neither}}$

Steps

Step 1 ：Substitute x = 3 and y = 15 into the equation: $15 = 7*3 - 2$

Step 2 ：Simplify the right side of the equation: $15 = 21 - 2$

Step 3 ：Further simplify the right side of the equation: $15 = 19$

Step 4 ：The equation does not hold true for the pair (3,15)

Step 5 ：Substitute x = -1 and y = -10 into the equation: $-10 = 7*(-1) - 2$

Step 6 ：Simplify the right side of the equation: $-10 = -7 - 2$

Step 7 ：Further simplify the right side of the equation: $-10 = -9$

Step 8 ：The equation does not hold true for the pair (-1,-10)

Step 9 ：$\boxed{\text{Therefore, the correct answer is (D) Neither}}$
