Question

show that A(3,1) B(6,4) C(8,6) Are colliner points ​

Answer 1

Answer:

If it is running with the same velocity it will cover 80km.

Step-by-step explanation:

8km in 1 liter

then it will cover 8*10 = 80km

Answer 2

Answer:

Condition for collinearity is

Ar(∆)=0

A=(3,1).........(x1,y1)

B=(6,4)........(x2,y2)

C=(8,6)........(x3,y3)

Ar(ABC)=1/2|x1(y2-y3)+x2(y3-y1)+x3(y1-y2)|

Ar(ABC)=1/2|3(4-6)+6(6-1)+8(1-4)|

Ar(ABC)=1/2|-6+30-24|

Ar(ABC)=1/2|-30+30|

Ar(ABC)=0

Therefore A,B and C are collinear.
