Question

Find the equation of the line joining(1,2) and (3,6) using determinants

Answer 1

Step-by-step explanation:

Let P(x,y) be any point on the line joining points A(1,2) and B(3,6)

Then, the points A, B and P are collinear. Therefore, the area of triangle ABP will be zero.

⇒6−y−6+2x+3y−6x=0

⇒y=2x

Hence, the equation of the line joining the given points is y=2x.
