प्रश्न
Give the equations of two lines passing through (2, 14). How many more such lines are there, and why?
उत्तर
It can be observed that point (2, 14) satisfies the equation 7x − y = 0 and x − y + 12 = 0.
Therefore, 7x − y = 0 and x − y + 12 = 0 are two lines passing through point (2, 14).
As it is known that through one point, infinite number of lines can pass through, therefore, there are infinite lines of such type passing through the given point.
