Answer 1

Verified answer

4x - 2y - 2 = 0

jika x = -2
4(-2) - 2y - 2 = 0
-8 - 2y - 2 = 0
-2y - 10 = 0
-2y = 10
y = -5

(-2, -5)

jika x = 2
4(2) - 2y - 2 = 0
8 - 2y - 2 = 0
-2y + 6 = 0
-2y = -6
y = 3

(2, 3) [D]

Answer 2

4x - 2y - 2 = 0

subtitusikan x = 2 ke pers. garisnya
4(2) - 2y - 2 = 0
8 - 2y - 2 = 0
2y = 8 - 2
2y = 6
y = 6/2
y = 3
jadi garis nya melalui titik (x,y) = (2,3)

subtitusikan x = -2 ke pers. garisnya
4(-2) - 2y - 2 = 0
-8 - 2y - 2 = 0
2y = -8 - 2
2y = -10
y = -10/2
y = -5
jadi garisnya melalui (x,y) = (-2,5)
