Tolong jwab yah kk ......

k. garis melalui ,(0,0) dan (3,1)
(y -0)/(1-0) = (x -0)/(3-0)
y/1 = x/3
x = 3y
x -3y = 0
l) (0,0),(2,2)
(y -0)/(2-0) = (x -0)/(2-0)
y/2 = x/2
2x = 2y
x = y
x - y = 0
m) (0,0), (-2,4)
(y -0)/(4-0) = (x -0)/(-2-0)
y/4 = x/-2
-2y = 4x
4x + 2y =0
2x + y = 0
n) (0,0), (-3,2)
(y -0)/(2-0)=(x-0)/(-3-0)
y/2 = x/-3
-3y = 2x
2x +3y = 0
