Gradien 1 =  \frac{-2}{3}

m₁=m₂=  \frac{-2}{3}

rumus nya : y-y₁=m(x-x₁)

y-4=  \frac{-2}{3} (x-(-2))

y =  \frac{-2}{3}x -  \frac{4}{3} + 4

y =  \frac{-2}{3}x +  \frac{8}{3}

semoga bener jawabannya :)
di obsen nya :
a.2x + 3y =-8
b.2x + 3y =8
c.2x + 3y =-4
d.2x + 3y=4
yauda berarti tinggal tiap ruas di kali 3 terus di pindah, jd jawabannya yg (B)

2x + 3y = 6 2(4) + 3(-2) =6 8 + (-6 ) = 6 2 = 6 = 6 -2 = 4 Maka, 2x + 3y = 4
