no 8
m1 = (2 - (-5))/(-1 - (-3)) = (2 + 5)/(-1 + 3) = 7/2
m2 = (2 - 4)/(7 - 0) = -2/7
tegak lurus karena m1.m2 = -1
yang lain sama caranya
maka akan menghasilkan
, dimana m adalah gradien dan c adalah konstanta
syarat:
a. 2 garis saling tegak lurus --> m1 x m2 = 1
b. 2 garis sejajar --> m1 = m2
8.
garis 1 (-3,-5) & (-1,2) --> (x1,y1)&(x2,y2)
garis 2 (0,4) & (7,2) --> (x1,y1)&(x2,y2)
gradien garis 1 = 7/2
gradien garis 2 = -2/7
m1 x m2 = 7/2 x -2/7 = -1
smpe disini udah paham?
