Question

Ajutor!Multumesc anticipat ​

Answer 1

Explicație pas cu pas:

$y = 2x - 6 \\ 2x - y - 6 = 0$

O(0;0) =>

$d_{1}: ax + by + c = 0 \\ d = \frac{ |ax_{O} + by_{O} + c| }{ \sqrt{{a}^{2} + {b}^{2}}} = \frac{ |c| }{ \sqrt{{a}^{2} + {b}^{2}}}$

$d = \frac{ | - 6| }{ \sqrt{{2}^{2} + {( - 1)}^{2}}} = \frac{6}{ \sqrt{5} } = \bf \frac{6 \sqrt{5} }{5}$
