Give the equations of two lines passing through (2, 14). How many more such lines are there, and why?

Here,

x = 2 and y = 14

Hence,

x + y = 16

Also,

y = 7x

y – 7x = 0

Therefore,

The equations of two lines passing through (2, 14) are:

x + y = 16

And,

y – 7x = 0

There would be infinite such lines because infinite number of lines can pass through a given point.
