Questions and Answers

Wat is die formule om die x-koördinaat van die mid-punt van 'n lyn te bereken?

$x = rac{x_1 imes x_2}{2}$

$x = x_1 + x_2$

$x = rac{x_1 + x_2}{2}$ (correct)

$x = rac{x_1 - x_2}{2}$

Wat is die formules om die y-koördinaat van die mid-punt van 'n lyn te bereken?

$y = rac{y_1 imes y_2}{2}$

$y = rac{y_1 + y_2}{2}$ (correct)

$y = rac{y_1 - y_2}{2}$

$y = y_1 + y_2$

Watter van die volgende is die korrekte uitdrukking vir die mid-punt M van 'n lyn?

$M(x, y) = rac{x_1 + x_2}{2}, y_1 + y_2$

$M(x, y) = rac{x_1 - x_2}{2}, rac{y_1 - y_2}{2}$

$M(x, y) = rac{x_1 + x_2}{2}, rac{y_1 + y_2}{2}$ (correct)

$M(x, y) = (x_1 + x_2, y_1 + y_2)$
