Question

Persamaan garis yg melalui titik (4,-6)
Dan sejajar dgn garis yg melalui titik (3, -4) dan (6,2) adalah,,,,

Answer 1

(y - y1) / (y2 - y1) = (x - X1) / (x2 - X1)
(y + 4) / (2 + 4) = (x - 3) / (6 - 3)
(y + 4) / 6 = (x - 3) / 3
3 (y + 4) = 6 (x - 3)
3y + 12 = 6x - 18
3y = 6x - 18 - 12
3y = 6x - 30
y = 2x - 15
m = 2

syarat sejajar m1 = m2 = 2
y - y1 = m (x - X1)
y + 6 = 2 (x - 4)
y = 2x - 8 - 6
y = 2x - 14
