A. m = y2 - y1/x2 - x1 m = 16 - 7/5 - 8 m = 9/-3 m = -3 b. m = y2 - y1/x2 - x1 m = -10 - 14/8 - (-4) m = -24/8 + 4 m = -24/12 m = -2 c. m = y2 - y1/x2 - x1 m = -9 - (-9)/-11 - 7 m = 0/-18 jadi gradiennya 0 d. m = y2 - y1/x2 - x1 m = 14 - (-10)/-21 - (-12) m = 14 + 10/-21 + 12 m = 24/-9 m = -8/3
m = 16 - 7/5 - 8
m = 9/-3
m = -3
b. m = y2 - y1/x2 - x1
m = -10 - 14/8 - (-4)
m = -24/8 + 4
m = -24/12
m = -2
c. m = y2 - y1/x2 - x1
m = -9 - (-9)/-11 - 7
m = 0/-18
jadi gradiennya 0
d. m = y2 - y1/x2 - x1
m = 14 - (-10)/-21 - (-12)
m = 14 + 10/-21 + 12
m = 24/-9
m = -8/3
