Two groups of friends are hiking. On a coordinate grid of the area, marked in 1 mile squares, one group is at (-2, 3). Another group has hiked to (4, -1) on the same coordinate grid. If the two groups want to meet at the halfway point for lunch, to what coordinates will they travel?

a. (3, 2)
b. (3, -1)
c. (-2, 4)
d. (1, 1)

anonymous · Answer

use the midpoint formula to solve...$$\left\{\left( x _{1}+x _{2} \right)/2  ,  \left( y _{1}+y _{2} \right)/2 \ \right\}$$

anonymous · Answer

x=(-2+4)/2=1
y=(3-1)/2=1
(1,1)
