T(4,10) is the midpoint of CD. The coordinates of D are (4, 18). What are the coordinates of C?​​

Respuesta :

The coordinate of C is (4, 2)

coordinate of C;

The formula for calculating the midpoint T is expressed as:

[tex]T(X, Y) = \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}[/tex]

Get the

X = x1+x2/2

4 = 4 + x2/2

8 = 4 + x2

x2 = 8 - 4

x2 = 4

Get the coordinate of y2

Y = y1+y2/2

10 = 18 + y2/2

20 18 + y2

y2 = 20 - 18

y2 = 2

Hence the coordinate of C is (4, 2)
