Question

determine if the point (1,5),(2,3),(-2,-11) are collinear​

Answer 1

Answer:

Step-by-step explanation:

A(1,5),B(2,3)andC(−2,−11)

Now, AB=(12 )+(22 ) =  5

​  BC=  (42 )+(142 )  = 212

​  CA= (12  )+(162 )  =  257

​

As,CA>BC>AB

If points A,BandC are collinear then AB+BC=CA

But  

     5  +  212  =  257

​  So they are not collinear.

if it help so plese mark it as brianlist and like it . i dont want follower but just want to increase the knowlage.
