Складіть рівняння прямої ,яка проходить через точку А(-3;1) паралельно прямій 5х+ 3у= 6​

* * *Составьте уравнения прямой, которая проходит через точку А (-3; 1) параллельно прямой 5x +3y =  6  * * *

" Решение " :  5x + 3y = 6  ⇔ y  = (-5/3)x + 2  

||  привели к виду y = kx+b   ,    k  = - 5/3  , b  =2  ||

Уравнения прямой, которая проходит через точку А (-3; 1) и параллельно прямой  y  = (-5/3)x + 2  имеет вид :

* * * у -y₀ = k₀ (x - x₀)   ,    x₀ = -3 ; y₀ = 1 ;  k₀ = k = -5/3   * * *

y - 1  = (-5/3)*(x - (-3)  ⇔ y - 1  = (-5/3)*(x +3) ⇔ y - 1 =  (-5/3)*x - 5

y  = (-5/3)*x - 4      

иначе   5x + 3y  +12 = 0           ( Ax + By +C =0→ общий вид  )
