Question

Persamaan garis yang melalui tirik {{{{{}{{(-2, 5) dan sejajar garis x - 3y + 2 = 0 adalah

Answer 1

Garis x-3y+2 = 0
m = 1/3
melalui titik (-2,5)
y-y₁ = m (x-x₁)
y-5 = 1/3 (x+2)
y-5 = 1/3x + 2/3
-------------------------- x3
3y-15 = x + 2
3y-x-17 = 0
x-3y+17 = 0

Answer 2

M = - a/b
    = - 1/(-3)
    = 1/3

Persamaan garisnya:
y - 5 = (1/3)(x - (-2))
3y - 15 = x + 2
x - 3y + 17 = 0
