x1= 2 y1= 3
x2= 6 y2= 8
(y2 - y1) / (x2 - x1)
(8 - 3) / (6 - 2)
5 / 4 atau 1 1/4
Jadi, gradiennya adalah 5/4 atau 1 1/4.
b. (-4,5) dan (-1,3)
x1= -4 y1= 5
x2= -1 y2= 3
(y2 - y1) / (x2 - x1)
(3 - 5) / (-1 - (-4))
-2 / (-1 + 4)
-2 / 3
Jadi, gradiennya adalah -2/3.
a).
m = ( 8 - 3 ) : ( 6 - 2 )
= 5 : 4
= 5/4
b).
m = ( 3 - 5 ) : ( -1 - (-4) )
= -2 : 3
= -2/3
