Question

1. give an equation of two lines passing through (3,12) how many more such lines are there and why

Answer 1

(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.

Answer 2

(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.
