gradien garis yang melalui titik (2,-6) dan (-2,4) jawab pke caranya

gradien = (y2 - y1)/(x2 - x1)
               = (4 - (-6))/(-2 -2)
               = 10/-4
                = -5/2

(2 , -6) = {x1 , y1}
(-2 , 4) = {x2 , y2}

Gradien
= y2 - y1 / x2 - x1
= (4 - (-6)) / (-2 - 2)
= 10/-4
= -10/4
= - 2 2/4
= -2 1/2
