persamaan garis
P(-3, 5) m - 4/5
y -y1 = m(x -x1)
y - 5 = -4/5 ( x + 3)
5( y-5) = - 4( x + 3)
5y - 25 = -4x - 12
5y + 4y - 25 + 12 =0
5y + 4x - 13 = 0 -
2. Jawaban Kivimaki
x₁ = -3
y₁ = 5
m = - 4/5
y - y₁ = m( x - x₁ )
y - 5 = -4/5( x + 3 )
—————————— ×5
5( y - 5 ) = -4( x + 3 )
5y - 25 = -4x - 12
5y + 4x = - 12 + 25
5y + 4x = 13
5y + 4x - 13 = 0 [ opsi. D ]
