Question

If walmart is the midpoint between BP and Greenfield Village (GV), what are the coordinates of GV?

Walmart Coordinates: (4,-4)
BP Coordinates: (1,-10)

Answer 1

(7,2)

Explanation:

First we need to figure out how far Walmart is from BP.

we can do this with some subtraction:

(this is simple because the coordinates are both in the same quadrant, if they weren't in the same quadrant the process would be a tiny bit different)

for x:

(4) - (1)=3

for y:

since the y's are both negative, we need to set the equation up carefully so we don't get the wrong number.

(-4) - (-10)

a double negative is the same as a positive so -4+10=6

That means Walmart is (3,6) away from BP. to figure out the coordinates of GV we can add (3,6) to Walmarts coordinates, (4,-4).

for x:

4+3=7

for y:

-4+6=2

That means the coordinates of GV are (7,2)

hope this helps :D
