Question

Persamaan garis yang melalui titik (3,2) dan sejajar garis 2x-4y=3 adalah...

Answer 1

Rumus cepat
2x-4y = 2x-4y
2x-4y = 2(3) -4(2)
2x-4y = 6 - 8
2x-4y = -2

Answer 2

2x-4y = 3
m = 1/2

y-y1 = m (x-x1)
y - 2 = 1/2 (x - 3)
y - 2 = 1/2x - 3/2
y = 1/2x - 3/2 + 2
y = 1/2x - 3/2 + 4/2
y = 1/2x + 1/2
2y = x + 1
