Verified answer
Diketahui gradien -2/3 dan melalui titik (3,4). Masukkan kedalam persamaan: y - y₁ = m(x - x₁), maka:=> y - y₁ = m(x - x₁)
=> y - 4 = -2/3(x - 3)
=> y - 4 = -2/3x + 2
=> y = -2/3x + 6 atau 3y + 2x - 18 = 0 atau 3y + 2x = 18 (sama saja)
Verified answer
Y - y1 = m (x - x1)y - 4 = -2/3 (x - 3) --> kali 3
3y - 12 = -2 (x - 3)
3y - 12 = -2x + 6
3y + 2x = 6 + 12
3y + 2x = 18
Atau
3y + 2x - 18 = 0
