On a map, Mary's house is located at (−3, 1) and the grocery store is located at (5, 7). Mary walks on a straight line from her
FrozenT [24]

The ordered pair that  represents the halfway point between Mary's home and the grocery store is (1, 4)

The midpoint (a, b) between two linear points (x_1, y_1) and (x_2, y_2) is calculated as:

a=\frac{x_1+x_2}{2} \\\\b=\frac{y_1+y_2}{2}

On a map, Mary's house is located at (−3, 1) and the grocery store is located at (5, 7).

x_1=-3, y_1=1, x_2=5, y_2=7

Substitute these values into the mid-point formulae

a=\frac{-3+5}{2} \\\\a=\frac{2}{2}\\\\a=1

b=\frac{1+7}{2} \\\\b=\frac{8}{2}\\\\b=4

The ordered pair that  represents the halfway point between Mary's home and the grocery store is (1, 4)
