tentukan gradien garis yang melalui titik titik berikut a(4,0)dan(0,3) b.(6,0)dan(2,8) c.(-7,6)dan(4,3) d.(-5,-3)dan(-4,-6)

a) m = (y2 - y1) / (x2 - X1)
m = (3 - 0) / (0 - 4)
m = 3 / - 4 = - ¾

b) m = (y2 - y1) / (x2 - X1)
m = (8 - 0) / (2 - 6)
m = 8 / - 4 = - 2

c) m = (y2 - y1) / (x2 - X1)
m = (3 - 6) / (4 + 7)
m = - 3 / 11 = - 3/11

d) m = (y2 - y1) / (x2 - X1)
m = (-6 + 3) / (-4 + 5)
m = - 3 / 1 = - 3
