Question

Find the x-coordinate of the midpoint for a line segment with endpoints at A (6 , 2) and B (19 , 12).

Your answer should be a single number. Round to the nearest tenth if needed.

Answer 1

12.5

Explanation:

The x-coordinate of a midpoint with given endpoints
`(x_1, y_1)` and
`(x_2, y_2)` is given by the formula
`x_M = \frac{x_1 + x_2}2`.

Substituting the given points' coordinates:

`x_M = \frac{6 + 19}2 \to \frac{25}2 \to 12.5`
