[tex] x_{1} [/tex] = -1
[tex] x_{2} [/tex] = 3
[tex] y_{1} [/tex] = 2
[tex] y_{2} [/tex] = -2

y - [tex] y_{1} [/tex] / [tex] y_{2} [/tex] - [tex] y_{1} [/tex] = x - [tex] x_{1} [/tex] / [tex] x_{2} [/tex] - [tex] x_{1} [/tex]
y - 2 / -2 - 2 = x + 1 / 3 + 1
y - 2 / -4 = x + 1 / 4
4(y - 2) = -4(x + 1)
4y - 8 = -4x -4
4x + 4y - 4 = 0

x + y - 1 = 0 (E)

Maaf klo salah
