Question

give the equation of two lines passing through
22.14) How many
more such lines are there
and why a​

Answer 1

Given point is (3,12)

⟹x=3,y=12

The lines formed can be x+y=3+12=15,x−y=3−12=−9

The two lines passing through (3,12) are x+y=15,x−y=−9

Also y=4x,5x−y=3,⋯ lines passes through (3,12)

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