George drove 12 miles south and 9 miles east. Using a coordinate plane to represent his trip, let the y-axis run north and south, let the x-axis run east and west, and let his original position be the intersection of the axes. Which ordered pair best represents his final location? 

 The ordered pair three comma negative four. 

 The ordered pair negative four comma three. 

 The ordered pair negative twelve comma nine. 

 The ordered pair nine comma negative twelve.

hmmm hold on, sorry, im helping someone else through email as well lol

anonymous · Answer

lol that's fine take your time :)

anonymous · Answer

the answer is "D", the reason being is because the Y-axis runs north and south (north being positive, south being negative) and the X-axis runs east to west (east being positive, west being negative) then what you do is take the 12 miles SOUTH, so that would NEGATIVE 12 and then take 9 miles EAST, so that would be POSITIVE 9
