Question

Find the equation of a line on which the point (1, 3) lies

Answer 1

Step-by-step explanation:

Go in a reverse order of middle term splitting...

If (1,3) is a point,

It means x-1 and x-3

now the equation be like...

$x (x - 3) \: - 1(x - 3)$

${x}^{2} - 3x - 1x - 3$

Futher we get...

SUM PRODUCT

-3 + (-1) (-3)(-1)

=(-4) = (-3)

We know the sum and product from above statement...

${x}^{2} - sum \: x + product$

Replace sum and product...

we get...

${x}^{2} - 4x - 3$

We got the equation...
