Question

Gradien garis yang melalui titik m (11,5) dan titik n (5,-3) adalah...

Answer 1

(x1,y1) = (11,5)
(x2,y2) = (5,-3)

Penyelesaian

m = (y2-y1)/(x2-x1)
m = (-3-5)/(5-11)
m = (-8)/(-6)
m = 4/3

Answer 2

M (11,5) maka x1 = 11 y1 = 5
n (5,-3) maka x2 = 5 y2=-3

gradien = (y2-y1)/(x2-x1)
             = (-3 - 5)/(5-11)
             = -8/-6
             = 8/6 (sederhanakan,sama-sama dibagi 2)
             = 4/3
             = 1  1/3
