Question

Determine a distancia entre as retas de equaçôes y = 3x - 1 e 6x - 2y +15 = 0



me ajudem oloco

Answer 1

6x-2y+15....(:2)...3x-y+15/2=0 
A=3.....B=-1.....C1=-1.....C2=15/2 

d= C2 - C1 / √A²+B² 

d=15/2 +1 / √3²+1² 

d=(17/2) / √10 

d=17/2 . 1/√10 

d=17/2√10.. ou.. 17/2. √10/10 = 17√10 /20
