Question

Give the equation of two lines passing through (3,15)

Answer 1

$\huge\red{\underline{{\bf Answer : }}}$

$\implies\sf$ 5x-y = 0 and x+y=18

● $\large\bold{Solution :}$

Equation of two lines pass through this point,

$\implies\sf$x = 3 and

$\implies\sf$y = 15 are solutions of both the lines.

Hence , 5x-y=0 and x+y = 18 are two equations of two lines passing through(3,15).

Answer 2

Answer:

(3,12)

Here x = 3

And, y = 12

So, the possible equations formed can be:

x + y = 15

x - y = -9

xy = 36

There are infinitely many lines passing through(3,12). Since infinitely many lines can be drawn through a given point.
