TOLONG BATU JAWAB SEMUANYA YA :)

A. garis AB
titik a (-4,-3)= x1= -4. y1= -3
titik b (5,3)= x2=5 y2=3
Mab=y2-y1/x2-x1 = 3+3/5+4 = 6/9 = 2/3
B. garis PQ
titik p (-4,-1)= x1= -4. y1= -1
titik q (6,6)= x2=6. y2=6
Mpq= y2-y1/x2-x1 = 6+1/6+4= 7/10
C. garis RS
titik r (5,-4)= x1.= 5 y1= -4
titik s (-2,7)= x2= -2 y2= 7
Mrs= y2-y1/x2-x1=7+4/-2-5 = 11/-7 = 1 4/7
maaf jika salah
