Instructions pour la figure interactive: La figure montre la droite de vecteur directeur
\(\vec{s}\) ainsi que les vecteurs correspondant aux lignes de la matrice
\(B\text{.}\) Un clic sur « Faire apparaitre/disparaitre le plan » fera apparaitre le plan engendré par les combinaisons linéaires des lignes de la matrice
