8y+4 x -16 = 0 8y = -4x +16 y = (-4/8)x +2 y = (-1/2)x +2, maka gradien = -1/2 karena garis sejajar maka gradien sama. y -y1 = m (x - x1) y - -3 = -1/2(x -5) y + 3 = -1/2x +5/2 y = -1/2x +5/2 -3 y = -1/2x +5/2 -6/2 y = -1/2x -1/2 atau 1/2x + y +1/2 = 0 x +2y +1 = 0
Verified answer
8y + 4x - 16 = 08y = -4x + 16
y = -1/2x + 2
m = -1/2
syarat sejajar
m1 = m2 = -1/2
melalui (5, -3)
persamaan garis h
y - y1 = m(x - x1)
y - (-3) = -1/2(x - 5)
y + 6 = -1/2 x + 5/2
2y + 12 = -x + 5
x + 2y + 12 - 5 = 0
x + 2y + 7 = 0
Verified answer
8y+4 x -16 = 08y = -4x +16
y = (-4/8)x +2
y = (-1/2)x +2, maka gradien = -1/2
karena garis sejajar maka gradien sama.
y -y1 = m (x - x1)
y - -3 = -1/2(x -5)
y + 3 = -1/2x +5/2
y = -1/2x +5/2 -3
y = -1/2x +5/2 -6/2
y = -1/2x -1/2
atau 1/2x + y +1/2 = 0
x +2y +1 = 0
