Question

Determine if the points (-4,3),(0,3) and (2,3)

are collinear ?​

Answer 1

yes these points are colinear .

let state , (-4 ,3) be the point A

(0,3) be the point B

(2,3) be the point C

by distance formula , we get

AB = root of / (0 -(- 4) )^2 + ( 3-3) ^2

= root of / 4^2

A B = 4

BC = root of / ( 2-0)^2 + ( 3 -3)^2

= root of / 2 ^2

B C = 2

AC = root of / ( 2- (-4)) ^2 + ( 3-3)^2

= root of / 6 ^2

AC = 6

SO, by this to check wheether they are colinear or not

AB + BC = AC

4 + 2 = 6

so they are colinear
