tentukan persamaan garis: 1. melalui (5,5) dan sejajar 3x - 2y = 6 2. melalui (-2,-1) dan tegak lurus garis y = -3x + 4 kalo yg ga bisa, mending ga usah jwb!

1. ax + by = ax1 + by1
3x + (-2)y = 3(5) + (-2)(5)
3x - 2y = 15 - 10
3x - 2y = 5
2. y = -3x + 4 → -3x - y + 4
bx - ay = bx1 - ay1
-x - (-3)y = 1(-2) - 3(-1)
-x + 3y = -2 + 3
-x + 3y = 1

1. * gradien:
3x - 2y = 6
m= -a/b
= -3/-2
m=3/2

* persamaan garis
y-y1 = m (x-x1)
y-5 = 3/2 (x-5)
y-5 = 3/2x - 15/2
y = 3/2x - 15/2 + 5 |×2
2y = 3x - 15 + 10
2y = 3x - 5
semoga membantu:)
