plot the points M(5,-3),N(-3,-3).what is the length of MN ,also find the co-ordinates of a points A,B,C lying on MN such that MA=AB=BC=CN ?

Question

CLASS 9TH MATHS 

COORDINATE GEOMETRY

Answer 1

M(5,-3),

 

N(-3,-3)

 

MN=8

 

Todivide MN into 4 equal parts we need three points A,B, and C

 

Length of  MA=AB=BC=CN=8/4=2

 

M and are having same Y coordinate so the line is parallel to X axis.N is on left side of M.

 

A=(5,-3)-(2,0) =(3,-3)

 

B=(3,-3)-{2,0)=(1,-3)

 

C=(1,-3)-(2,0)=(-1,-3)

 

You can verify the answers by calculating the distances to observe MA=AB=BC=CN=2!!!!!!!!!

 

Thank you
