Question

Прямая задана A(1;2), B(-4;-3). Найти координаты точки С, если В – середина АС.

Answer 1

Пусть координаты С будут ( х : у ) , тогда по правилу нахождения середины...... ( х + 1 ) / 2 = -4 .... х = -9 .......... ( у + 2 ) / 2 = - 3 ..... у = - 8 . Ответ координаты С (- 9 : - 8 )

Answer 2

Finding the Coordinates of Point C

To find the coordinates of point C, which is the midpoint between points A(1,2) and B(-4,-3), we can use the midpoint formula:

Midpoint Formula: The midpoint between two points (x1, y1) and (x2, y2) is given by the coordinates: ((x1 + x2)/2, (y1 + y2)/2)

Applying the Midpoint Formula

Using the coordinates of points A(1,2) and B(-4,-3), we can calculate the coordinates of point C:

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

Therefore, the coordinates of point C are (-3/2, -1/2).

This calculation is based on the midpoint formula and the given coordinates of points A and B. [[7]](https://onlinemschool.com/math/library/analytic_geometry/points_center/)
