subebe
X -2y +12 =0 13. 2y = x +12 y = 1/2 x + 6 gradien =1/2 karena sejajar maka gradien 1 =gradien 2 =1/2 y - 7 = 1/2(x - 2) y = 1/2 x - 1 + 7 y = 1/2 x +6 2y = x + 12 2y - x -12 = 0 (jawaban C) 20. y=2x + 3 gradien = 2 garis h y - 3 = 2(x-2) y - 3 = 2x - 4 y = 2x -1 (jawaban D)

13. 2y = x +12
y = 1/2 x + 6
gradien =1/2
karena sejajar maka gradien 1 =gradien 2 =1/2
y - 7 = 1/2(x - 2)
y = 1/2 x - 1 + 7
y = 1/2 x +6
2y = x + 12
2y - x -12 = 0 (jawaban C)
20. y=2x + 3
gradien = 2
garis h
y - 3 = 2(x-2)
y - 3 = 2x - 4
y = 2x -1 (jawaban D)
