Question

Calcule a distância da reta P a reta ,r tendo o ponto p (1,3)e a reta r:3× + 4y-5=0

Answer 1

$d = \frac{ |axp + byp + c| }{ \sqrt{ {a}^{2} + {b}^{2} } } \\ d = \frac{ |3.1 + 4.3 - 5| }{ \sqrt{ {3}^{2} + {4}^{2} } }$

$d = \frac{10}{ \sqrt{9 + 16} } = \frac{10}{ \sqrt{25} } = \frac{10}{5} = 2$
