Perhatikan keterangan berikut.

Jawab:

Garis i : melalui titik (-3,5) dan titik (6,2)

m = y2-y1/x2-x1

m = 2-5/6-(-3)

m = -3/9

m = -1/3

Garis j : melalui titik (5,-2) dan titik (2,7)

m = y2-y1/x2-x1

m = 7-(-2)/2-5

m = 9/-3

m = -3

Garis k : melalui titik (-2,-4) dan titik (1,5)

m = y2-y1/x2-x1

m = 5-(-4)/1-(-2)

m = 9/3

m = 3

Garis l : melalui titik (-4,-3) dan titik (5,-6)

m = y2-y1/x2-x1

m = -6-(-3)/5-(-4)

m = -3/9

m = -1/3

jawaban : garis i dan l
