Question

You start a search for a buried object by marking the center of a field as (0, 0), with coordinates giving distances in yards. Coordinates to the north or east are positive and coordinates to the south or west are negative. You find nothing at (–12, 8), so you try a likely-looking spot 3 yards to the east and 11 yards to the south of the first spot. What are the coordinates of the second spot?


(–15, –3)


(–15, 19)


(–9, –3)


(–9, 19)

Answer 1

You're at (-12, 8)

you go 3 east, that means you're going towards the right

so the x-value is going to be -12 + 3 = ??

and then you go 11 south, that means you're going down

so the y-value changes and is going to be 8 - 11 = ??
