Question

(1 , 3) (2 , 6) (3,9) what is relation between these two Of bar graph

Answer 1

let A (1 ,3) B (2 ,6) and C (3,9)

slope of AB=(6-3)/(2-1)=3/1=3

slope of BC=(9-6)/(3-2)=3/1=3

slope of AC=(9-3)/(3-1)=6/2=3/1=3

hence
slope of AB =slope of BC=slope of AC
hence all AB , BC and AC line's graph is parellel to each other .
