A. y -y₁ = m(x -x₁) y -1 = 2/3(x -1) y -1 = 2/3 x -2/3 dikali 3 untk menghilangkan penyebut, sehingga 3y -3 = 2x -2 3y = 2x -2 +3 3y = 2x +1 b. y -y₁ = m(x -x₁) y -5 = 3(x -0) y -5 = 3x y = 3x +5 c. y -y₁ = m(x -x₁) y -2 = 0(x -(-2)) y -2 = 0 y = 2
y -1 = 2/3(x -1)
y -1 = 2/3 x -2/3 dikali 3 untk menghilangkan penyebut, sehingga
3y -3 = 2x -2
3y = 2x -2 +3
3y = 2x +1
b. y -y₁ = m(x -x₁)
y -5 = 3(x -0)
y -5 = 3x
y = 3x +5
c. y -y₁ = m(x -x₁)
y -2 = 0(x -(-2))
y -2 = 0
y = 2
