tolong ya bantu,, jawabnya blh lwat twitter ato fb q, twitter @sevtawinanthi fb Eka Sevta

m=(y1-y2)/(x1-x2)

a) (4,3) dan (-2,-5)
x1=4, x2=-2, y1=3, y2=-5

m=(3-(-5))/(4-(-2))
m=(3+5)/(4+2)
m=8/6
m=4/3
m=1⅓

b).(-1,-1) dan (7,-3)
x1=-1, x2=7, y1=-1, y2=-3

m=((-1)-(-3))/((-1)-7)
m=(-1+3)/(-1-7)
m=2/-8
m=-¼
