Question

A straight line having equal intercepts from the co-ordinate axes and passes through $(2,4)$ then find the equation of the line.

Answer 1

Let $a$ be the equal intercepts from the co-ordinate axes.

Then the equation of the line will be $x+y=a$.

According to the problem the line passes through $(2,4)$ then we get,

$a=6$.

So the equation of the line will be $x+y=6$.
