Someone help with this question please

Answer:
D
Step-by-step explanation:
x goes in intervals of 7 and y goes in intervals of 2
so we know that the next pair's x coordinate has to be 2 more or less from the last pair and the y coordinate has to be 7 less or more than the last pair (the last pairs would be (-4,-14) and (4,14)
so we can cancel out c and b because it doesnt match with the intervals
which leaves us with a and d and a is wrong because only 6 is negative and 21 is not so it wouldnt fit because the next pair has to be both negative or positive cause thats where the last two pairs ended so d is the answer
and we can check d because if you continue the relationship from (4,14) the and add 2 on hte x value would be 6 and if you add 7 to the y value it would be 21 which is D
