Question

If the point A(1,2),B(0,0),C(a,b)are Collinear, then find the relation between a and b. plz send me the answer... plz..

Answer 1

Answer:

The relation between a and b is 2a=b. It means b is twice of a or a is  half of b.

Step-by-step explanation:

The given points are A(1,2),B(0,0),C(a,b).

These points are collinear if slope of AB is equal to BC.

Slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of AB is

$m_1=\frac{0-2}{0-1}=2$

The slope of BC is

$m_2=\frac{b-0}{a-0}=\frac{b}{a}$

If A,B, and C are collinear, then

$m_1=m_2$

$2=\frac{b}{a}$

$2a=b$

Therefore the relation between a and b is 2a=b. It means b is twice of a or a is  half of b.
