Question

Persamaan garis yg sejajar dengan garis 6y = 3x + 2 dan melalui titik (-4,-5) adalah

Answer 1

6y = 3x + 2

y = 3/6x + 2/6
y = 1/2x + 1/3

m = 1/2

y - b = m(x - a)
y -(-5) = 1/2(x -(-4))
y + 5 = 1/2(x + 4)
y + 5 = 1/2x + 2
2y + 10 = x + 4
2y = x + 4 - 10

2y = x - 6

atau

2y - x + 6 = 0

atau

2y - x = -6

Answer 2

6y = 3x + 2
m = 3/6
= 1/2

m1 = m2

y - y1 = m (x - x1)
y + 5 = 1/2 (x + 4) --> kali 2
2y + 10 = 1 (x + 4)
2y + 10 = x + 4
2y - x = 4 - 10
2y - x = -6
