Question

Find a relation between x and y, if the points (x,y), (1,2) and (7,0) are collinear. (Do this using distance formula)

Answer 1

Answer:

Step-by-step explanation:

HI

YOUR ANSWER IS

Since A(x,y),B(1,2),C(7,0) are collinear  

Slope of AB= Slope of BC

1−x

2−y

​  

=  

7−1

0−2

​  

 

1−x

2−y

​  

=  

3

−1

​  

 

3(2−y)=−1(1−x)

6−3y=x−1

x+3y−7=0
