Question

the midpoint of a line segment in the coordinate plane is ____________. a single number. never a decimal or a fraction. an ordered pair. rewatch submit

Explanation:

In a coordinate - plane, if the endpoints of a line segment are $(x_1,y_1)$ and $(x_2,y_2)$, the mid - point formula is $(\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})$, which is an ordered pair. A single number cannot represent a mid - point in a two - dimensional plane. Also, mid - points can be decimals or fractions.

Answer:

an ordered pair.
