Tolong jawab soal yg ada di gambar

1. D. 2y + 4x =0
2. C. 2
3. D. (2,3)
$4x - 2y - 2 = 0 \ jika : x = 2 \ 4(2) - 2y - 2 = 0 \ 8 - 2y - 2 = 0 \ - 2y + 6 = 0 \ - 2y = - 6 \ y = frac{ - 6}{ - 2} = 3$

4. 2x + 4y + 4 = 0
a = 2, b = 4
$m = frac{ - a}{b} = frac{ - 2}{4} = frac{ - 1}{2}$

5. 4x-2y-7
a=4,b=-2
$m = frac{ - a}{b} = frac{ - 4}{ - 2} = 2$
