Question

Give the equqtion of two lines passing through(2,14) . How many lines can pass through the point?

Answer 1

let x=2;y=14

then equations of two lines passing through(2,14)-

1. 7x-y=o

2.2x=y=18

S||y, there are infinite lines which can pass through the point (2,14).

Answer 2

let x=2 and y = 14
therefore, some equations are :
x + y = 16     => x + y - 16 =0
x - y = -12     => x - y + 12 = 0
7x - y = 0
7x + y =  28

there are infinite numbers passing through a single point
